I have to laugh when instructors talk repeatedly about muzzle discipline and then regularly point their pistols over the berms during numerous activities and have their students follow with the same actions.
I get a sick feeling in my stomach when i see a muzzle rise over the berm.
I always stress that we are fully responsible for that bullet that just left our barrel.
I am very very seldom wrong when i point out 50 and older and say I will be on you when your muzzle rise over the berm AND the range (read County Pit) is a 75 ft. bank and we shoot at targets @21 ft with berm/bank 25 yards beyond target. And I call them all and all those that have been military trained still have a wrist flick that will go over this high bank! every single class!!
