9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...
In both the open and standard rifle divisions, minor power factor is dominating due to less recoil, and 5.56×45mm/ .223 Rem is a common caliber. Ammunition loaded to major power factor such as 7.62×51 mm/ .308 Win has a bigger recoil impulse, and is regarded as having an advantage on stages with targets at long range.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
There, a 115 only needs to be going a bit over 1,500 ft/s to qualify for major power factor. Competitors in the late 1980s and early 1990s who were using the 9×25mm Dillon used the additional powder available over .38 Super to produce more gas in the compensator, or muzzle brake , to make pistols shoot with as little muzzle rise as possible to ...
This is a list of firearm cartridges that have bullets in the 9 millimeters (0.35 in) to 9.99 millimeters (0.393 in) caliber range.. Case length refers to the round case length.
A Minor power factor carried scoring penalties and so there was an incentive to make the Major qualification. As the power factor calculation is proportional to bullet momentum and as the very large proportion of recoil is proportional to bullet momentum, it is immediately clear that the 9×23mm Winchester had essentially the same power factor ...
Competitors may declare major with a 9mm (.355") bullet loaded to a power factor of 170, [9] but a maximum of 6 rounds can be fired before a reload is required. From 2017, there is no limit on the number of rounds fired before a reload is required, but revolvers with a capacity of 7 rounds or more will automatically be scored as Minor power factor.
Also the muzzle energy is only an upper limit for how much energy is transmitted to the target, and the effects of a ballistic trauma depend on several other factors as well. There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 ...
