Come on people, do it right or don’t do it at all. You don’t put your finger on the trigger unless you are ready to shoot. And what makes it worse is this is a kid. Now this kid will never have good trigger finger discipline.
Look, know your weapon and know your loads. There are two things wrong with this clip. The first is that if this guy has never shot before he has a-holes for friends as he just split his lip and maybe lost a tooth. You don’t let friends get hurt with firearms.
If this was his gun, he really needs to take it slow and figure out what he can safely handle. I’d start with a .410 and work up to the 12G buddy.
