Hello, My first posting on this board, brand new member. I have a question for you Johnson shooters. I picked up one for my brother many years ago, which I wish I could have afforded to keep then, but glad for my bro. Anyway, when we've fired it, it rips the heck out of the rims, making the brass useless. Is this a normal treatment of it's brass? Someone recently advised to oil the cartridges prior to loading in the rifle. He's down in the Republic of Calif, so hasn't had a chance to try this yet. Any observations. Thanks and regards, Guns
