Re: Rem 700 SPS 7mm Rem Mag Re-chamber to 7mm RUM
Don't do it! The RUM is a high-pressure round, wear as the regular mag is not. And now you are going to cut the chamber out even thinner? I believe that the RUM rums at least 15,000psi higher pressure. I'd never trust the now thinner-walled lower grade steel to stand up to the 15 K increase in pressure. You need to get one that is already an ultra, just like I do. But you simply can't get the rem 84155 right now. I called them and was told production starts in April, available in May.
