I have a cva optima that's about 13-14yo and last year I used it then let someone else use it so didn't clean it when I gave it to them. well when I got it back I forgot to clean it and its been in the basement since January. I use hodgdons 777. I know its dirty but im wondering is this barrel now ruined? im playing with the idea of buying a new version of mine but money is tight and part of me says just deal with the things I don't like about mine but if the barrel is shot then I will have to buy the new one Saturday.
