I have a friend that has one and it started key holing along with bad accuracy. Being 22mag, I gave him the idea of having a 17 HMR liner installed.
I kind of doubt that he has done it yet, but that might be an option for you.
Just a thought, re-lining us usually fairly reasonable! Probably could reline it with a 22 liner and re chamber it also.
Just a thought, those are nice rifles.
