SinterFire Bullets are for the discerning reloader who wants to shoot indoors and outdoors, up close on steel or any shooter valuing a lead-free training experience. All SinterFire lead-free, frangible projectiles are manufactured using an exclusive blend of copper and tin composite material and a proprietary heat treatment process. SinterFire is the originator and innovator of this technology used by government, military and law enforcement personnel since 1998.
Unlike conventional lead projectiles, which ricochet or fragment into large pieces, SinterFire projectiles disintegrate into small particles upon impact with surfaces harder than themselves. Since the projectiles are lead-free and frangible, they are ideal for close quarter training on steel plates and in tactical houses. This is not loaded ammunition.
