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. On the other hand, recoil is subjective (some are more sensitive to it than others) and one can get used to it with practice. The Winchester's factory ammunition for the .300 Winchester Magnum is capable of 990 m/s (3,260 ft/s) with the 150-grain (9.7 g) bullet and 910 m/s (3,000 ft/s) with the 12-gram (180 gr) bullet, however old Western "Power Point" soft point can reach past 1,000 metres per second (3,400 ft/s) with 9.7 g (150 gr) projectiles. Since its introduction the cartridge has remained extremely popular. 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. On my comp rifle, I have 28" and 30" barrels to utilise very slow powders for extra velocity, 200-300fps is typical. The test protocol was simple.

Jewell Trigger, Spuhr Mount with Schmidt-Bender PMII 5-25x56 Illuminated P4 Fine. 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. C.I.P. Barrel length, Barrel length and velocity, Cartridge Selection, Precision Rifles, Rifles The 300 Win Mag’s short case neck is not detrimental to accuracy, and it is actually capable of near bench-rest like groups with the proper load in a high quality rifle. The rifle was zeroed at 100-yards and the testing began. However, the.300 Ultra Mag also has a lot more recoil than the.300 Win Mag. After bore sighting the rifle and confirming zero at 50-yards. [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.

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. Elk can weigh as much as 450 kilograms (1,000 lb) and moose 640 kilograms (1,400 lb). Its recoil is about 30% greater than that of the .30-06 Springfield,[11] which is known as a 'stout' cartridge. The amount of recoil the cartridge generates is a step up from the non-magnum .30 caliber (7.62 mm) cartridges. 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). This would put the .300 Winchester Magnum at the upper limit of what most shooters can shoot comfortably for extended shooting sessions. Weight of the rifle, including bipod, optic and mount was 18.28 pounds with a 24.25 inch barrel. UPDATE: 1/1/15, see below for 308 Winchester and 223 Remington.

Mag., which has been roaming the fields since 1964, cranks that up to 2,950 fps and 3,478 f-p energy. Due to the power and performance of the .300 Winchester Magnum cartridge the cartridge is more likely to be employed by specialist units within a police department rather than as a general service weapon issued to law enforcement agents. Recommended twist ratio is 1:10 (254 mm). The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being surpassed in performance by the more powerful .300 and .30-378 Weatherby Magnums and the newer .300 Remington Ultra Magnum.

The most useful bullet weights for the .300 Winchester Magnum are those weighing between 150–200 grains (9.7–13.0 g). The rifle is fired at 100 yards, from a bipod with a rear bag, for 5-rounds. The two most important variables are the Initial Velocity and the Ballistic Coefficient. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet. The .300 Win. Standard deviation generally decreased as the barrel got shorter. Winchester's factory load gives a 165 grain Fail Safe bullet a MV of 3120 fps and ME of 3567 ft. lbs. Most, while well informed, are based off of data extrapolation and comparing a few different barrel lengths on dissimilar rifles. Mag. In C.I.P. I developed a mild headache from the 50 rounds of ammunition I shot, despite wearing both ear plugs and muffs. 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. So, it begs to question whether or not the new .300 PRC will steal the thunder of the .300 Win. The .300 Weatherby Magnum is a fast, hard-hitting cartridge, driving a 180-grain bullet to a muzzle velocity of 3250 fps, for over 4,000 ft.-lbs. If the .300 Winchester were given a magnum-length receiver, where a longer bullet could be seated properly, it could utilize these longer bullets without issue. Remington 88.0 grains of H2O (5.70 ml) 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 projectile diameter should be 0.309 in (7.85 mm) [8]. The initial barrel length was 24.25 inches. Recoil and muzzle blast increased significantly when the barrel reached 20.25 inches in length and again below 18.25 inches. If Winchester had released the cartridge prior to 1960, the cartridge would have been similar to the .30-338 Winchester wildcat cartridge. 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. 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. Barnes and edited by M.L. The ability to zero the .300 Winchester Magnum and shoot without hold over to 270 metres (300 yd) makes the cartridge one of the flatter shooting cartridges. As a rough comparison, the recoil of the .300 Winchester Magnum is roughly comparable to a 12 gauge shotgun shooting 1 oz. Does red dot brightness (and bloom) change point of impact? and SAAMI dimensional values exist for this cartridge. This results in a flatter trajectory, more resistance to wind drift, and more retained energy at longer range. 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. SAAMI recommends a bore diameter of 7.6 millimetres (0.300 in) and a groove diameter of 7.8 millimetres (0.308 in).

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. For four ammunition manufacturers the cartridge case capacities are provided as: This greater recoil can make the .300 Winchester Magnum, despite its inherent accuracy advantages, a harder cartridge to shoot accurately, when compared to non-magnum .30 caliber cartridges such as the .30-06 Springfield or the .308 Winchester. 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. Wildcatters soon produced the .30-338 Winchester and Norma Projektilfabrik, who were by now manufacturing ammunition for Weatherby, took the standard length basic Weatherby brass and necked it down to .30 caliber (7.62 mm) and called it the .308 Norma Magnum. This caused the cartridge to have a neck shorter than the diameter of the bullet. Mag. The .300 Winchester Magnum was designed with a neck which is shorter than the diameter of its bullet. The .300 Winchester uses the same case head design of the .375 H&H Magnum, its parent cartridge. Each reduction in barrel length averaged 39.6 ft/sec in velocity loss. Quite unexpectedly the new cartridge featured a much longer case than the .338, as long as could be housed in a Winchester long action, in order to achieve optimum velocities. 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.

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. 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. The popular .30 caliber's omission from that lineup was not missed. [13], The .300 Winchester Magnum cartridge is very effective on dangerous class 3 game such as bear. So, the.300 Win Mag is slightly more powerful, has a slightly flatter trajectory, and has somewhat more recoil than the.30-06. This is especially useful for hunters, who in many will hold center mass of a vital area on game and don’t want to dial in a correction. 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.

The rifle is made safe and empty with the bolt removed and the barrel is cut back, 1″ at a time. 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. The rifle became easier to handle at the expense of decreased ballistic performance and increased recoil, muzzle flip and blast. 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).
