In IPSC competitions all handguns must have a power factor of at least 125 kgr·ft/s (≈ 2.47 newton seconds), and therefore almost anything of 9×19mm or greater caliber will meet the minimum required power factor. The minimum power factor rule is designed to mitigate the speed and accuracy advantages of smaller calibers.
Although not originally designed for handguns, several rifle and shotgun cartridges have also been chambered in a number of large handguns, primarily in revolvers like the Phelps Heritage revolver, Century Arms revolver, Thompson/Centre Contender break-open pistol, Magnum Research BFR, and the Pfeifer Zeliska revolvers.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
The .460 S&W round is a lengthened, more powerful version of the popular .454 Casull, itself a longer and more powerful version of the .45 Colt.For this reason, the .460 S&W Magnum can be considered an example of a "super magnum".
The first selected was the 9mm described above. The second was a ".45 round, Remington 185 grain hollow point". The Wound Ballistic Workshop participants had a "consensus" that hollow points with "superior penetration" was what was needed. The 10mm was picked as a "halfway" between the other two options, in terms of size.
Changing the diameter of the case (to suit a new caliber). Called "necking up" or "necking down", this is the most common way of making a wildcat. The new caliber allows a different range of bullet weights, and can greatly increase the velocity or the power or the resistance to wind drift as compared to the parent cartridge. Necking back.
The .357 SIG (designated as the 357 Sig by the SAAMI [2] and 357 SIG by the C.I.P. [1] or 9×22 mm in official metric notation) is a bottlenecked rimless centerfire handgun cartridge developed by the Swiss-German firearms manufacturer SIG Sauer, in cooperation with ammunition manufacturer Federal Premium.
Announced to the public in early 1996 at an NRA convention, the 9×23mm Winchester cartridge was claimed to have the lowest recoiling load and still qualify for Major Power Factor designation in the IPSC. [2] [4] The IPSC Power Factor (PF) is equal to bullet weight in grains times muzzle velocity divided by 1,000. A PF of at least 175 was ...
