Barrel was fine at about 1300. Started using RL17, very rough first 4" and greatly extended throat in 200-250 shots. Changed back to RL22, adjusted COL and its back to ragged hole but fouls badly. I'll shoot it till it dies which I suspect will be soon.
Replacement will be a factory take off - I want to use it and practice a lot.
How much is a replacement barrel? I'm just wondering if is better to just get another rifle.
