| 説明 | Select All sizes and check the original 3.*k x 2.*k and you can see the rifling in the barrel of the gun. Apparently the smooth-bore for Armor Piercing Discarding Sabot (APDS) rounds was superseded by a rifled barrel gun and High Explosive Anti Tank, (HEAT), ie a shaped charge, fitted with slipping bands so the rifling wouldn't make it spin too fast to function. |
