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 ...
"Grain foot per second" (gr·ft/s) can be obtained by measuring the mass in grains (gr) (7,000 to the pound) and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1 ⁄ 1000, obtaining the power factor in kilo grain foot per second instead.
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.

It is designed to be run wet or dry, averaging 127.7–128.4 dBA with 147 grain or 127.6–134.2 dBA with 124 grain when dry and 123.1 dBA with 147 grain or 129.1 dBA with 124 grain when wet. [86] It is an additively manufactured titanium weapon suppressor. It is 50% lighter than some conventional steel suppressors [81] The Israel drum magazine ...
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Cordite is a type of firearm propellant using shaped pieces rather than a powder form.. Firearm propellants are a specialized type of propellant used to discharge a projectile (typically a bullet, slug, or pellets) through the barrel of a firearm.
Bullets in the 110- to 120-grain range are suitable for small game and varmints (handloads with 110s can nearly achieve 3000 ft/s); 120- to 154-grain range for deer; and 154 to 168 gr range are adequate for larger game at closer ranges.
