Currently A-square is the only other factory ammunition producer of the .340 Weatherby Magnum, which has led to limited popularity of the caliber. In field tests the .340 clearly outperforms the 300 Ultra mag, .338 Win mag. and even rivals the larger .375 H&H, providing a much flatter shooting and harder hitting performance.
The .30-378 Weatherby Magnum is a .30 caliber, belted, bottle-necked rifle cartridge. [2] The cartridge was developed in response to a US Army military contract in 1959. While still unreleased to the public, the cartridge went on to set world records for accuracy including the first ten 10X in 1,000 yards (910 m) benchrest shootin
In 2009, Barnes developed a new bullet specifically for use in the .458 SOCOM, the 300 grain Tipped Triple Shock X, also known as the TTSX or TAC-X. As noted above, the cartridge was designed to be 100% compatible with the M4 platform. This included the buffer, buffer spring, NATO magazines, many aftermarket .223/5.56 magazines, and magazine ...
Bullets ranging in weight from 100 gr (6.5 g) to 115 gr (7.5 g) should be chosen for these deer species. Although the .257 Weatherby is used as an elk and moose cartridge with success in North America, the cartridge is thought of as being ill-suited for these heavier deer, with elk weighing on average 700 lb (320 kg) and moose on average ...
Monolithic bullets such as the A-Square Monolithic Solid, [23] Barnes Banded Solid, [24] Supreme Nosler Solid [25] and more conventional tougher FMJ bullets such as the Hornady DGS [26] are good choices as they are able to withstand stresses placed on the bullets by the velocity of the .460 Weatherby Magnum. At the 250 yd (230 m) mark, the .460 ...
The Double Tap achieves 2,825 ft/s (861 m/s) and 4,700 ft⋅lb (6,400 J) with a 270-grain Barnes TSX from a 23-inch barrel Ruger 77 African. The .375 Ruger's greater case capacity, and the "short fat" cartridge efficiency lead to increases in the neighborhood of 150 to 200 fps over the .375 H&H Magnum cartridge.
The Varmint and Predator load hold 60-grain Hornady V-MAX bullets. The 80.5-grain Gold Medal Berger Match was designed for long-range target shooting. The 78-grain Barnes TSX copper hollow point is a hunting round for large game such as deer. [17]
The typical 300 gr (19 g) ammunition manufactured by Federal and Remington have a muzzle velocity of 2,530 feet per second (770 m/s) churning out 4,263 ft⋅lbf (5,780 J) of energy. The 300 gr (19 g) ammunition has a bullet trajectory similar to that of the .308 Winchester firing a 180 gr (12 g) bullet. The trajectory allows for a MPBR of about ...
