Sonic Boom's 1 lb Exploding Rifle Target provides one of the largest explosions and loudest booms of any exploding target on the market. The highly visible blaze orange jar makes seeing this target easy at virtually any distance. The two-part mixture is easy to mix and easy to use - simply mix and shoot. To ensure safety, shooters must be at least 100 yards from this exploding target before shooting. To initiate explosion, this rifle target must be struck with a center fire rifle projectile, weighing at least 40 grains and traveling at a minimum of 2200 fps (pistol rounds will not initiate this target). For best performance, Sonic Boom suggests using a FMJ (Full Metal Jacket) round. | Sonic Boom 1 lb Exploding Rifle Target
