Lighter bullets require more gunpowder weight to achieve the necessary velocity compared to heavier bullets using the same gunpowder, resulting in more gas for the compensator. Brands like JJR Ammo, ORM Tech and Universal Ammo typically use 115–124 gr (7.5–8.0 g) bullets in their 9mm Major ammunition.
An expanded 124-grain 9×19mm Parabellum jacketed hollow point The round was originally designed to be lethal to 50 metres (160 ft), but is still lethal at longer ranges. [ 22 ] The 9×19mm Parabellum cartridge combines a flat trajectory with moderate recoil .
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 ...
"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 bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. ... 115-grain (7.5 g) – FMJBT; 130-grain (8.4 g) – soft point;
Most shooters, looking at the 9×25mm Dillon today, focus on the extreme velocities of which it is capable. A 115-grain bullet at 1,800 fps is more than is needed for competition. There, a 115 only needs to be going a bit over 1,500 ft/s to qualify for major power factor.
