So, after looking around my gun room, I find, inter alia, a pre war greifelt marked for 2-1/2 inch shells that has been opened to 2-3/4, with a kersten cross bolt and double underbolts (just like a Merlel); a couple of pre war 2-3/4 inch sidelock Merkels and a post war 303 sidelock Merkel. Also a 1911 vintage Winchester 1897 and a 1921 model 12 and a number of Berettas from the 1960s. I won't get into some of the other stuff. I have never reloaded and have always used whatever ammo came from the store, usually the cheapest stuff around. Other than going to hell, what's likely to happen to me for totally disregarding proper loads etc.?
