Yeah, I love Mike. But he's not the last word on things. Sometimes even he gets it wrong.
He needs to adjust his technique a bit. He was trying to blame the capper and the caps but it is just the way he's doing it. Also, he's blaming the capper for the caps falling off the gun under recoil. That's just absurd. You watched him push every cap on with his stick, and two caps still fell off. That's a cap fitment issue, not the cappers fault. It's also part of the reason why he was having such a hard time putting the caps on. The caps are too loose on those nipples.
