Not sure about you, but I've had many folks take my rifle, and after showing and telling them how to hold it, they completely ignored my warning/instructions and ended up with the typical moaning and groaning, along with a " I heard a bone crunch! " line after they pulled the trigger. It's almost sickening when they do it with a conical load, because I know that hurt worse!
That crescent butt plate is not made to my shot like your typical shotgun or centerfire with a nice flat squishy pad! Stop tuckin the butt plate into your arm pit!
