I had the sissy pad

Figured I would try to get off to a start without a flinch. I think my trigger control and flinchig were generally not horrible (paid a lot of attention to it, worked on being surprised at discharge, caught a few flinches early as they were about to happen). Have to test it with some dummy rounds.
I do think the eyesight played a roll. The target was a grey blob unless I squinted, then the sight picture blurred while I held the squint. The high shooting is a common issue (most battle rifles initially set to zero at 150 - 200 yards) and a hot barrel and the loose stock/receiver bolt couldn't have helped. In any case, getting tight is going to involve some practice.
Pad or not, the Mauser had a stiff recoil. I hear the Enfield is not too bad. And I expect my heavy M39 to be pretty tame. It was a totla blast regardless (pun intended) and can't wait to make another day of it. Shot a hundred through the .357 while I was there.
