SinterFire
Copper-tin frangible training ammunition with a lead-free primer for approved close-steel and indoor use.

SinterFire GreenLine loads a 100-grain copper-tin composite projectile with a lead-free primer. SinterFire says its frangible projectiles disintegrate into small particles when they strike a surface harder than the bullet, which reduces hard-target ricochet and splash during approved training. The exact 50-round load is listed at 1,230 fps.
GreenLine is the all-lead-free training branch of the SinterFire line. It fits indoor and close-steel programs that require both a lead-free projectile and primer, but it is still live ammunition. Follow the range and target maker's rules, then test cycling and point of impact before using it for a full class.
