The .577 BPE originated around 1870 with the 2 1 ⁄ 2-inch variant. [1]The 3-inch cartridge has survived to the current day as the .577 Nitro for Black, the same cartridge loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.
Smith & Wesson then decided the 10mm Auto was too much cartridge for the reduced power loading, and that the .45 ACP sized guns that chambered it were too heavy and bulky; out of this came the .40 S&W, a shortened 10mm Auto case, designed to fit in a 9mm-sized gun, with a reduced pressure loading that allowed a lighter, easier to shoot gun.
The .270 Weatherby Magnum was the first belted magnum based on the .300 H&H Magnum to be developed by Roy Weatherby in 1943. [2] The cartridge is short enough to function in standard-length long actions with a brass length of 2.549" or 64.74mm and an overall length of about 3.295".
Recently Weatherby has offered some reduced loads in the 7,500 ft⋅lbf (10,200 J) range, in order to be more forgiving to shooters. [47] The recoil of the full-power loads is very punishing and if the gun has a scope, scope cuts on the forehead are common. [48] A factory powder charge for this cartridge is about 115 grains (7.5 g).

The annual volume is renowned for its comprehensive firearms reviews, manufacturer listings, and current firearm values guide.
Single-shot express rifles, such as the Ruger No. 1 Tropical, are more compact than bolt-action rifles, but while they usually weigh less, the reduced weight tends to increase the felt recoil. Lighter rifles are more likely to be in the hunter's hands, ready for a quick shot when game is located.
The added -30 stands for the standard load of 30 grains (1.9 g) of early smokeless powder and is based on late-19th century American naming conventions for black powder-filled cartridges. Both Marlin and Union Metallic Cartridge Co. also dropped the Winchester appellation, as they did not want to put the name of rival Winchester on their products.
The .40 S&W (10.2×22mm) is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and Winchester in 1990. [3] The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi ...
