It MIGHT not hurt so much if the butt plate on my 1895 CB Marlin was replaced with a super soft pad but I want to keep it original except for the Skinner sight. The stock lever hurts my hand as well but I can put a DRC glove loop lever on it and still have the stock one too. The heavy load is a handful in my sons Ruger #1 a well. Yeah, I guess I'm a bit wimpy in my old age but so be it! I don't care who you are, you can shoot the lighter loads more accurately.
armednfree, you are right to build muscle memory with the rifle and there is a lot to be said for fast, but remember, fast is good but fast and accurate is golden. Good luck brother.
