I think the best thing to do would be to contact CVA regarding how much you can load them. Used to have one in 4570 and it was an amazing rifle, overbuilt and sturdy. When i emailed them a long while back, they said something (honestly don't remember), but i do remember according to my loading book, i remember it being in the middle. It can be above powder puff stuff, but they said they wouldn't hot rod it lile a ruger one or something like that. That being said though i was taking a 405gr lead cast flat nose and was using a relatively stout load. Truth be told, i got tired long before my rifle ever did. I only lowered my loads because i couldn't handle the recoil, the rifle was a champ though!
