I like Lone Wolf , They have factory polished feed ramp , full case support , tighter tolerances than stock , but not so tight a tolerance like KKM where reliability comes into question. I read a write up where the lug sheared off a storm lake , the guy got a replacement from factory and that lug sheared off as well . Could it have been one off glitch in that round of production? sure but it was enough to keep me from buying one. BTW Not saying Storm Lake arn't good barrels .
