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. , 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 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).

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.

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) . 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.

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.

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. , 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.
