With the bolt charged and the safety on, I slammed the butt on the floor several times and it stayed firm.
The proper safety check is:
-cock rifle, pull trigger, : fires at Correct weight = ok
-cock rifle, safety on, pull trigger high force: no fire/no movement = ok
-then safety off, pull trigger: should fire with same feel = ok
-cock, slam bolt : no fire = ok (reconfirm pull trigger = fire)
-cock, drop test : no fire = ok (reconfirm pull trigger = fire)
*this one is the hardest because dropped hard enough on the butt, I think all guns will fire. Also, at some drop height, the stock will crack
-cock, safety on, drop test : no fire = ok (reconfirm pull trigger = fire)
-cock, side/rear pressure: no fire = ok (reconfirm pull trigger = fire)
