BT, DT. Hand-gun rounds bounce, badly, do not do that! On center .223's simply drill in and disappear, off-center they ricochet and become really dangerous too. .308 Norma Mag blows off chunks when hit off-center. Never hit it on-center, so no idea about that.In case you can’t hit a golf ball use a bowling ball, they explode when hit with a 30 cal.
Makes a Mell of a Hess, do this on a range that is easy to clean afterwards.
