The .300 Win Mag is based off the parent case .375 H&H Magnum with a belted largerifle magnum primer. This results in a flatter trajectory, more resistance to wind drift, and more retained energy at longer range. Speed and Trajectory: The big difference here is that the 300 win mag will send a 180 grain bullet, which is at the top end of the 308’s abilities, at almost 3000 fps. My long ranger: Surgeon 1086 Long Action in 300 Winchester Magnum. The U.S. government purchased MK 248 MOD 1 .300 Winchester Magnum match-grade ammunition in 2009 for use in adapted M24 Sniper Weapon Systems and other .300 Winchester Magnum sniper rifles like the U.S. Navy Mk.13s. Keep in mind almost two pounds came off the muzzle end. Sorry, your blog cannot share posts by email. OTM Match Grade Rifle Ammunition, My bolt won’t close! The Weatherby's standard length magnum case was soon noticed. Select specific calibers and cartridges by using the filters 2. Elk can weigh as much as 450 kilograms (1,000 lb) and moose 640 kilograms (1,400 lb). There is overlap between the rounds of the different cartridges, and this trend continues through the entire 500-yard range, but we do see an average higher velocity for the .300 WM over the .30-06. Recoil and muzzle blast increased significantly when the barrel reached 20.25 inches in length and again below 18.25 inches. The maximum point blank range for the 12 g (180 gr) bullet is 300 yards when zeroed at 232 metres (254 yd). My follow up article is here Does size matter? Barrel length, Barrel length and velocity, Cartridge Selection, Precision Rifles, Rifles The 16.25 inch barrel only having 12.3 inches more of drift at that distance. is known for—and it’s more than enough to kill a whitetail at 150 yards, and without punishing a smaller person. [27] However, by the time Winchester got around to designing their own .300, the .308 Norma Magnum and the .30-338 were already on the scene. We headed to the range with a 300 Winchester Magnum, a chronograph and my hacksaw. regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. Many consider the .300 Winchester Magnum to be on the lighter side of what is required for the largest bears, but hunters have had success with the cartridge against these large bruins.[16]. Prior to the design of the .300 Winchester Magnum there were several cartridges that provided what could be best described as a magnum level of energy. The down side to this performance is recoil. December 25, 2013 SAAMI recommends a bore diameter of 7.6 millimetres (0.300 in) and a groove diameter of 7.8 millimetres (0.308 in). [12] It is particularly useful when hunting the members of the ungulate family such as elk and moose and is a popular cartridge among hunters for these class 3 game species. Military and law enforcement departments adopted the cartridge for long range sniping and marksmanship. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) have provided specifications for the .300 Winchester Magnum cartridge. So, what does this mean downrange? Finally, the lure of potential internet greatness set in and I decided to pull the trigger. Bill Marr C.I.P. [citation needed] However, bullets weighing between 7.1–16.2 g (110–250 gr) are available to the reloader for the .300 Winchester Magnum. Elk can weigh as much as 450 kilograms (1,000 lb) and moose 640 kilograms (1,400 lb). Discussing the methodology with friends, I originally envisioned stopping around 20″, cutting off the chamber end of the barrel and using it for a 308. I have a Tikka 300 Win Mag and use the Noslar 180 gr Ballistic Tip and Accubond, both run at 2960 fps out of the 24 inch barrel. This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the 220 gr (14.26 g) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 2,850 ft/s plus or minus 50 ft/s (869 m/s ± 15.2 m/s). Troubleshooting seized ejectors. The ballistic performances based off five grain types for velocity are 3,260 ft/s(1… If deformation of the lead nose in the magazine box is a problem, our 180 grain Protected Point Partition or AccuBond bullets are good options. https://en.wikipedia.org/w/index.php?title=.300_Winchester_Magnum&oldid=994984252, Short description is different from Wikidata, Articles with unsourced statements from July 2019, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 December 2020, at 15:58. I am only interested in Hodgdon and IMR powders as they are the only ones I have access to. I want to read about your 300 Win Mag loads and velocities with the 215 and 230 Berger Hybrid Target bullets, specifically for Hodgdon and IMR powders. [13], The .300 Winchester Magnum cartridge is very effective on dangerous class 3 game such as bear. With bullets of good sectional density and ballistic coefficients the cartridge possesses the long range performance necessary to take large game species at extended ranges. [9] Both the .300 Win Mag and 7mm Rem Mag have specific rounds that show a much higher velocity and also rounds that fall lower on the graph. This created the much criticized short neck of the .300 Winchester Magnum. To put this into perspective, a Boeing 737 commercial airliner travels at a cruising speed of 600 mph, or 880 fps. Few .30 caliber (7.62 mm) standard length cartridges can match the performance and versatility of the .300 Winchester Magnum. Its recoil is about 30% greater than that of the .30-06 Springfield,[11] which is known as a 'stout' cartridge. While there may be differences in the effects on the quarry from the velocity, the difference in maximum point- blank range is relatively small  (34 yards) between the 24.25 (327 yards) and 16.25 inch (293 yards) barrels. Maximum effective range is generally accepted to be 1,210 yards (1,110 m) with ammunition incorporating low-drag projectiles. Almost no divergence between C.I.P. No other accurizing work has been performed. The heritage of .30 caliber (7.62 mm) magnums can be traced back to the .30 Newton in 1913 and to the .300 H&H Magnum in 1925. The velocity and energy figures in this table are taken from various sources including the Federal, Remington, Weatherby and Winchester ammunition guides and the 9th Edition of the book Cartridges of the World by Frank C.

[22], In January 2014, the U.S. Department of Defense annual testing report found that the older A191 or MK 248 Mod 0 .300 Winchester Magnum service round loaded with aerodynamically less efficient 190 gr (12.32 g) Sierra MatchKing Hollow Point Boat Tail (HPBT) bullets fired from the XM2010 demonstrated adequate performance and lethality. The.308 Win. Each reduction in barrel length averaged 39.6 ft/sec in velocity loss. Sub 1 minute-of-angle (MOA) accuracy out to 1,000 yards (910 m) is not unusual in precision-built rifles firing match-grade ammunition. There was no power at the range so a chop box was out of the question. A Shilen #8 contour chrome-moly barrel had been threaded and chambered on the gun. The short neck was thought to hinder accuracy because it would prevent the alignment of cartridge to the bore, but this is rarely an issue either today or when the cartridge was designed. Mag. Norma Bondstrike Ammunition 300 Winchester Magnum 180 Grain Polymer Tip Boat Tail Box of 20. Compared with the 30-06 Springfield the .300 Winchester Magnum provides a roughly 400 ft/s (120 m/s) increase in velocity. Notably, the .300 Win Mag cartridge fires a projectile that on average can best the .308 Winchester cartridge by 50% on overall distance while maintaining lethality. After bore sighting the rifle and confirming zero at 50-yards. Based on a 308 Winchester case, the 6.5 mm (.264″) Creedmoor fits inside an AR10/ 308 AR platform and feeds well […]. has a big appetite for propellant, burning 20 to 25 percent more propellant for only a 10 percent increase in velocity over the .30-’06 Sprg. The test protocol was simple. I’m going to install a brake, crown the barrel the right way and be the proud owner of a 16.25 inch 300 Winchester Magnum barrel… I’m unsure I’ll shoot it much, if at all, but at least I can definitively tell someone what happens when you cut your 300 Winchester Magnum to 16.25 inches. Post was not sent - check your email addresses! In some cases, the point of impact was unchanged. Due to the short neck, heavier bullets particularly those weighing greater than 13 grams (200 gr) and mono-metal bullets such as the Barnes X bullets will need to be seated more deeply into the cartridge. Hunters found the cartridge to be an effective all-around choice with bullet options ranging from the flatter shooting 165 grain to the harder hitting 200+ grain selections available from the factory. To help differentiate it from the other .300 magnums, and to allow for the chambers of the standard length .300 magnums to be rebored to the .300 Winchester Magnum chamber dimensions, Winchester moved the shoulder forward and lengthened the cartridge slightly. 300 Winchester Magnum: How Does Barrel Length Change Velocity- A 16″ 300 Win Mag? It has the same 2.85-inch case as the.375 H&H, requiring a magnum-length action, but it also has plenty of case capacity. On my comp rifle, I have 28" and 30" barrels to utilise very slow powders for extra velocity, 200-300fps is typical. UPDATE: 1/1/15, see below for 308 Winchester and 223 Remington. The .300 Winchester Magnum was designed with a neck which is shorter than the diameter of its bullet. The two most important variables are the Initial Velocity and the Ballistic Coefficient. [4] It is a popular selection for hunting moose, elk, and bighorn sheep as it can deliver better long range performance with better bullet weight than most other .30 caliber cartridges. Mag., which has been roaming the fields since 1964, cranks that up to 2,950 fps and 3,478 f-p energy. and SAAMI dimensional values exist for this cartridge. Most, while well informed, are based off of data extrapolation and comparing a few different barrel lengths on dissimilar rifles. The velocity and standard deviation are recorded. This is the first day the gun will be fired. As illustrated in the chart, .300 Weatherby Magnum rounds - on average - achieve a velocity of about 3230 feet per second (fps) while .300 Winchester Magnum rounds travel at a velocity of 3030 fps. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the .300 Winchester Magnum can handle up to 430.00 MPa (62,366 psi) Pmax piezo pressure. That speed brings a nice, flat trajectory that makes it a bit easier to hit at long distance. The rifle became easier to handle at the expense of decreased ballistic performance and increased recoil, muzzle flip and blast. Winchester finally introduced the .300 Winchester Magnum in 1963. [7], The .300 Winchester Magnum's high availability in popular rifles such as Winchester's Model 70 and Remington Model 700 made the cartridge a popular choice among the shooting public. “The 300 Win. It is particularly useful when hunting the members of the ungulate family such as elk and mooseand is a popular cartridge among hunters for these class 3 game species. Great care has been given by Hornady engineers to develop superior, match­-accurate hunting loads that allow the ELD­-X ® bullet to achieve its maximum ballistic potential. This would put the .300 Winchester Magnum at the upper limit of what most shooters can shoot comfortably for extended shooting sessions. Winchester's factory load gives a 165 grain Fail Safe bullet a MV of 3120 fps and ME of 3567 ft. lbs. SAAMI recommended a six-groove barrel with each groove being 2.8 millimetres (0.110 in) wide. On the other hand, recoil is subjective (some are more sensitive to it than others) and one can get used to it with practice. PSA: Don’t melt your MagnetoSpeed with a suppressor! 300 Win Mag 200 gr ELD-X® Precision Hunter® Item #82002 | 20/Box .

In this article, we will start with a new Remington 700 short […], Introduction I cut back a 28″ barrel 308 Winchester one inch at a time, to 16.5″, and recorded velocity data for four different cartridges. A 3 ft/sec increase in muzzle velocity was recorded between the 22.25 and 21.25 inch barrels. At the range I looked at my shooting buddy and we decided to go all in and cut it to 16.25″. Mag. Both black bears[14] and grizzly bears[15] are hunted using the cartridge. The lengthening of the case and the move of the shoulder forward over the .338 Winchester Magnum allowed for the reaming of the .308 Norma Magnum or .30-338 Winchester chamber to dimensions of the .300 Winchester Magnum. The most useful bullet weights for the .300 Winchester Magnum are those weighing between 150–200 grains (9.7–13.0 g). Initially we (it’s always good to bring a friend with this much cutting) used a cordless Sawzall to make the cuts, after the battery died, we switched to a hacksaw. Federal 92.0 grains of H2O (5.96 ml) The popular .30 caliber's omission from that lineup was not missed. Although the .300 H&H Magnum, .30-338 Winchester Magnum and the .308 Norma Magnum had a head start on the .300 Winchester Magnum these cartridges soon faded into obsolescence. The contents of Rifleshooter.com are produced for informational purposes only and should be performed by competent gunsmiths only. However, the.300 Ultra Mag also has a lot more recoil than the.300 Win Mag. The down side was a neck which was shorter than the caliber of the bullet it fired, which meant that the bullet had to be seated more deeply in the case. Mag. of energy at the muzzle, it is far ahead of the .30-06 Springfield and .300 H&H Magnum. As the bullet will take up volume which could have been taken by the propellant velocity advantages diminish as the weight of the bullet increases. I would suspect the 178 gr would be very similar. Range conditions were good for a December day in the Northeastern USA. I hunt some tough terrain, I almost always have my 26" barreled 300 on my shoulder, my 338 also has a 26" tube, it comes with me every other trip. Hover over graphs and lines to see more d… [17][18][19] The 3.55 in (90.2 mm) long MK 248 MOD 1 or alike ammunition is not offered commercially, since it exceeds SAAMI standards for overall length and maximum chamber pressure. Several companies, among them HS precision, Kimber and Remington manufacture rifles chambered for the .300 Winchester Magnum specifically targeted at law enforcement agencies. The Weatherby cartridges involved blowing out (reducing the taper) of the Magnum H&H cases, bottlenecking them to the required caliber and shortening them to fit the standard rifle actions of the era. Does red dot brightness (and bloom) change point of impact? The .300 Winchester Magnum is powerful enough to hunt any North American game animal. For instance, when calculating maximum point blank zero for a 8″ target, the projectile will never rise more then 4″ above the line of sight or 4″ below. Krieger Heavy Varmint (fluted) with JEC Custom Brake. Chronograph data was recorded using a MagnettoSpeed V2 barrel mounted ballistic chronograph. Mag., or become just another .300 magnum … If Winchester had released the cartridge prior to 1960, the cartridge would have been similar to the .30-338 Winchester wildcat cartridge. This means that .300 Winchester Magnum chambered arms in C.I.P. Lets take a look at drop and drift at 1,000 yards (the internet’s favorite distance) for each length barrel. Although cartridges such as the .30-378 Weatherby Magnum, .300 Remington Ultra Magnum and the .300 Weatherby Magnum all exceed performance of the .300 Winchester Magnum none of these cartridges can be chambered in a standard length action. Custom Remington 700 16.5″ 300 Winchester Magnum follow up, Blueprinting, or truing a rifle action ensures the receiver face, threads, lugs, bolt lugs and bolt face are square to the center line of the receiver. McPherson. Significant jumps in velocity reduction occurred between 18.25 and 16.25 inches (56, 65 ft/sec) and between 23.25 and 22.25 inches (65 ft/sec). Long popular with big game hunters, the 300 Winchester Magnum has also been adopted by the US military as part of the M24 Sniper Weapons System and Mk 13. I selected Federal 190 grain Gold Medal ammunition for this test. The amount of recoil the cartridge generates is a step up from the non-magnum .30 caliber (7.62 mm) cartridges. We cut it back at 1-inch intervals ending up with a 16.25 inch barrel. Due to its ability to shoot flat and carry its energy efficiently, the cartridge is one of the more favored rounds for African plains game. slugs. Since the 300 Winchester Magnum is a popular hunting cartridge, I also worked out the maximum point-blank zero for each barrel length with the given load assuming a 8″ vital area on deer sized game. So, it begs to question whether or not the new .300 PRC will steal the thunder of the .300 Win. Rifle. [3], The .300 Winchester is extremely versatile and has been adopted by a wide range of users including hunters, target shooters, military units, and law enforcement departments. If you liked this post subscribe to Rifleshooter.com (top right corner of page). The rifle is fired at 100 yards, from a bipod with a rear bag, for 5-rounds. The .300 Winchester Magnum can be used to hunt everything from the dik-dik to the giant eland. There has been some speculation that if the cartridge was released earlier, the dimensions of the cartridge would have matched the .30-338 Winchester wildcat cartridge. The ammunition standards organizations SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) and C.I.P. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. The .300 Winchester Magnum is powerful enough to hunt any North American game animal. The.300 Win. Standard deviation generally decreased as the barrel got shorter. That means it was 55 F, heavy rain, and overcast with mild 5 to 10 mile per hour winds. Norma 95.5 grains of H2O (6.19 ml), .300 Winchester Magnum SAAMI cartridge dimensions. A 165 grain bullet is probably a better choice for the.300 Win. Recommended twist ratio is 1:10 (254 mm). This was unexpected, but the target confirms these similarities with all 10-rounds landing within a 1.799″ inch group (the one fired by the 21.25″ barrel). I did periodically make scope adjustments to utilize different parts of the target, but in general, groups were within 1 inch of the group fired with the previous barrel length. Here is a list of the parts, as well as the Brownells part number: The contents of Rifleshooter.com are produced for informational purposes only and should be performed by competent gunsmiths only. Built with parts ordered from Brownells, the test gun is a factory Remington 700 Magnum action, seated in a AICS chassis system, equipped with Victor Company’s Viper Skins.

While it wouldn’t be your first choice for hunting ammunition, Federal Gold Medal works well, is widely available, and serves as a good standard for comparison. A commonly asked question on hunting, long range shooting and Mil/LE forums is, “how long should the barrel on a 300 Winchester Magnum be?”   I’ve been coming up short of any objective analysis of barrel length based off of actual data- i.e., cutting back the same barrel and publishing actual velocities. The .300 H&H Magnum was too long for the Mauser and Springfield standard length rifle actions and required specialized rifles with a Magnum size action. Firing the rifle with the 24.25 inch barrel was pleasant (for a belted magnum) with minimal muzzle rise. This was the first time the Pentagon's Director, Operational Test and Evaluation (DOT&E) tested the round, which can hit targets out to 1,200 m (1,312 yd).[23]. I developed a mild headache from the 50 rounds of ammunition I shot, despite wearing both ear plugs and muffs. Visit Brownells to accessorize your 300 Winchester Magnum. The rifle was zeroed at 100-yards and the testing began. Launching a 180-grain bullet to 2,925 fps, the.300 H&H betters the velocity of the.30-06 by more than 200 fps. is simply one of the most flexible cartridges for North America and African plains game,” Phil says. Also, many rifles available today now have effective recoil attenuating features built into them, such as muzzle compensators and energy absorbing stocks and butt-pads, that can significantly lessen recoil as it is felt by the shooter. Controlled expansion bullets such as the Nosler Partition or Barnes X are preferred rather than more lightly constructed bullets for these larger species of ungulate. The initial barrel length was 24.25 inches. [citation needed]. The SAAMI Maximum Average Pressure (MAP) for this cartridge is 441.3 MPa (64,000 psi) piezo pressure (54,000 CUP).

Weight (lbs) Accuracy International AICS-AX 2.0 Chassis System Review: Initial Thoughts, Does size matter? While the Federal Gold Medal 190 grain ammunition from the 16.25 inch barrel has a flight path 100 inches lower then the 24.25 inch barrel, the effects of a full value wind are less significant. The maximum point blank range for the 9.7 g (150 gr) bullet is 291 metres (318 yd) yards when zeroed at 250 metres (270 yd). This translates to about 20% greater energy advantage over the 30-06 Springfield cartridge. Jewell Trigger, Spuhr Mount with Schmidt-Bender PMII 5-25x56 Illuminated P4 Fine. The goal of this article is to help you determine which .300 Win Mag Rifle is best for you. Increase your rifle's performance up to 200 fps without extra chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy. If you do not have a Shooting Chronograph, I strongly suggest you purchase one. Just purchased a Rem 700 Sendero SFII, 300 WinMag with a 26" tube and a 1:10 twist. Cartridge Type: RifleHeight: 2.62\"Width: 0.532\"Average FPS: 3026Average Energy: 3517Average Gr: 173Recoil: 2.39Power Rank: 5.23 of 20 The .300 Winchester Mag (.300 Win Mag) was designed in 1963 by Winchester Repeating ArmsCompany. Ambient lighting was poor, we were barely able to read printed material from the firing line beneath overhead cover and it was 11 o’clock in the morning. According to the official C.I.P. All sizes in inches (in) and millimeters (mm). Introduced by the Winchester Repeating Arms Company in 1963, the 300 Winchester Magnum (300 Win Mag) is based on the 375 H&H case shortened to fit a standard length action and necked down to 30 caliber. The short, fat 300 WSM, released on an unsuspecting public in the second year of the 21st century, boosts that slightly to 3,010 fps and 3,621 f-p. If we were to take averages of all the rounds, then there would be a slight advantage to for the 7mm Rem Mag rounds at each yard marker and each time the difference is less than 100fps. The.300 Win Mag shoot heavier bullets at a higher velocity than the.30-06 (~200-300fps faster with the same bullet). It’s time to see what happens to the same gun, under the same conditions, as the barrel is set back one inch at a time. Mag., given the powder capacity of the case and the superior sectional density (SD) of the heavier bullet. They have amassed a lot of data on various cartridges (mostly handgun). defines the common rifling twist rate for this cartridge as 254 mm (1 in 10 in), 6 grooves, Ø lands = 7.62 mm (0.300 in), Ø grooves = 7.82 mm (0.308 in), land width = 2.79 mm (0.110 in), and the primer type is large rifle magnum. The rifle is fired at 100 yards, from a bipod with a rear bag, for 5-rounds. [20], According to JBM Ballistics,[21] using the G7 ballistic coefficient provided by Bryan Litz, and a Weapon Employment Zone (WEZ) analysis of the XM2010 rifle with various .300 Winchester Magnum ammunition types by Bryan Litz, the MK 248 MOD 1 .300 Winchester Magnum cartridge, when fired at its nominal muzzle velocity of 869 m/s (2,850 ft/s), should have 1,286 to 1,289 m (1,406 to 1,410 yd) supersonic range under International Standard Atmosphere conditions at sea level (air density ρ = 1.225 kg/m3). The science of projectiles and firearms, or in other words, the info you need to make the kill!If you are looking for the 270 vs 308 vs 30 06 ballistics chart, the 5.56 trajectory chart, the 300 Win Mag Ballistics data, or the 30 06 trajectory chart; you are in the right place!Here are a few suggestions for using the below dashboard: 1. However, the handloader can take advantage of modern advances in powder technology and actually exceed the velocity of the MK 248 MOD 1 cartridge while still loading to maximum SAAMI cartridge overall length, and maintaining safe pressure. It moves them at 3180 fps. The SAAMI specification .300 Winchester Magnum case capacity is 91.5 grains of H2O (5.93 ml). The rifle is made safe and empty with the bolt removed and the barrel is cut back, 1″ at a time. As a rough comparison, the recoil of the .300 Winchester Magnum is roughly comparable to a 12 gauge shotgun shooting 1 oz. wins here because it has the powder capacity to handle bullets as heavy as 220 grains, moving them as fast as 2,770 fps to generate a bone-crushing 3,800 ft lbs of energy. Live fire tests were conducted in March 2013 against ballistics gelatin, light material barriers, and other targets to determine the projectile's ability to perforate targets.
