From a reloader standpoint, there was tremendous versatility in the .40 Super. Bullet weights on the market included: 125, 135, 150, 155, 165, 170, 180, 190, 200 and 220 grains. Loads were developed with a dozen powders. Small pistol magnum or small rifle primers could be utilized. Brass was available from both Triton and Starline Brass Company.
The first step to firing a firearm of any sort is igniting the propellant. The earliest firearms were hand cannons, which were simple closed tubes.There was a small aperture, the "touchhole", drilled in the closed end of the tube, leading to the main powder charge.
According to Starline Brass, "The primer pocket was changed from large pistol primer to small pistol/rifle primer in 12/00. Test results concluded no adverse affect from switching to small primer pocket. Cor-Bon is now recommending Win. small pistol works best and if using small rifle Remington 7 1/2 works the best." [21]
Modern primers are basically improved percussion caps with shock-sensitive chemicals (e.g. lead styphnate) enclosed in a small button-shaped capsule. In the early paper cartridges , invented not long after the percussion cap, the primer was located deep inside the cartridge just behind the bullet, requiring a very thin and elongated firing pin ...
A Hi-Point JCP pistol. Hi-Point semi-automatic pistols are polymer framed handguns based on the blowback design. Different from other blowback design pistols such as the Walther PPK, the P-64, and the Astra 600 which use a heavy slide combined with a stiff recoil spring to hold the breech closed, these pistols use a heavier slide so they can use a softer recoil spring.
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
A large or small pistol primer is used. [7] [8] The CIP rulings indicate a maximum pressure of 230 MPa (33,000 psi). In CIP-regulated countries, every pistol/cartridge combination is required to be proofed at 130% of this maximum CIP pressure to certify for sale to consumers. [9]
0.175" (4.45 mm) diameter small pistol primers, and a thicker or stronger metal cup small rifle version for use with higher pressure loadings in weapons with heavy firing pin impact. 0.209" (5.31 mm) diameter primers for shotgun shells and modern inline muzzleloaders, using a Boxer-type primer factory-assembled inside a tapered, flanged brass cup.
