I'm in the process of sporterizing a 93 mauser. The barrel is trash it has been cut down and someone shot corrosive in it and let it sit so I'm going to make it into a .257 roberts. I have recently purchased a bolt that was bent in a way that I liked but it is really rough and I've got some work to do on it. I'm wondering if any of you guys have done this conversion yourself or if you have any advise. I'll keep you updated on my progress. I don't have bags O' cash so progress is slow.
