The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length.
The 9mm obrazetz 1911, was a 9mm pistol with a 3.9-inch barrel similar to the German Pistole 08 but lacking a grip safety, stock lug and with a lanyard loop on the lower left side of the butt; around 10,000 were ordered. After the Second Balkan War many of the 7,65mm Lugers were re-barreled to 9mm [76] [77]
Test barrel length: 26" Source(s): Accurate Powder [ 2 ] The 7mm Shooting Times Westerner , sometimes referred to as the 7mm STW , began as a wildcat rifle cartridge developed by Layne Simpson, Field Editor of Shooting Times, in 1979. [ 3 ]
Iron sighted pistols and revolvers with a maximum barrel length and sight radius of 381 mm (15 in), and a maximum weight of 2,041 g (4.5 lb). The sight radius is measured from the rear of the sight blade to the highest portion of the from sight. The overall length of the firearm can no more than 635 mm (25 in).
The 7mm BR was designed by merely necking up the pre-existing 6mm BR Remington to accept a .28 caliber (7 mm) bullet. The cartridge is capable of developing 2,200 ft/s (670 m/s) with a 139 gr (9.0 g) bullet or 2,100 ft/s (640 m/s) with a 154 gr (10.0 g) bullet in a 15 in (380 mm) barrel.
Subsequently, the case was shortened to reduce powder capacity to a volume more suited to the shorter barrel of a pistol. The resulting cartridge, the .221 Fireball, produced factory-loaded velocities of over 825 m/s (2,700 ft/s) from the short barrel, and accuracy rivaling the parent .222 Remington, one of the most accurate cartridges made.

Best performance is had with the rifle barrel; with the shorter carbine barrels the .30-30 is a better choice. [citation needed] With the long barrel, however, the 7-30 provides flatter trajectory, and a longer effective range, as well as reduced recoil from the lighter bullets. Despite the advantages, the 7-30 still lags far behind the ...
A schematic of the P7's gas-delayed blowback system.. The P7 is a semi-automatic blowback-operated firearm. It features a unique gas-delayed blowback system modeled on the Swiss Pistole 47 W+F (Waffenfabrik Bern) prototype pistol [6] (and ultimately on the Barnitzke system first used in the Volkssturmgewehr 1-5), [7] which used gas pressures from the ignited cartridge and fed them through a ...
