THROOM Targets can be shot with any caliber rifle or handgun.
It is bullet velocity that is the key:
Over 1,250 fps: shoot THROOM Targets at 75 yards or farther away; shooting closer will result in targets not reacting.
Between 750 fps and 1,250 fps: shoot THROOM Targets from 5 yards to 75 yards away.
Under 750 fps: do not use THROOM Targets with bullets traveling below 750 fps.
DO NOT USE THROOM Targets with pellet guns, BB or airsoft guns as the pellets or BBs may bounce back
