50 Rounds of .40 S&W Ammo by Prvi Partizan - 165gr FMJ

This 40 S&W cartridge by the Serbian ammunition manufacturer Prvi Partizan features a 165 grain bullet with a full metal jacket. It is perfect for the range and self-defense training for two primary reasons. First, its jacket will keep your bore protected so you can maintain tighter groupings for longer in between cleanings. Second, its flat nose will punch clean and easily visible holes through paper targets, so you can receive instant feedback on your progress without straining your eyes. Furthermore, this cartridge’s non-corrosive Boxer primed brass casing is optimal for reloading, so 50 of these should keep you content for quite some time.

The 40 S&W is favored among law enforcement professionals and self-defense experts for its marked energy advantage over the 9mm, as well as for its lesser recoil over the 10mm. A powerful enough 40 S&W has even been argued to be capable of inflicting hydrostatic shock in human-sized targets. Training with this cartridge will certainly prepare you for a worst-case scenario.
