I have one its a C.M. long act. in 416 rem., bbl. is S.S M.R.C. ,left hand bolt. I,m very pleased with it so far I have fired 411 rds. I have had a feeding prob. but it was a easy fix and the rifle works 100%. now. I also broke two leopold scopes but that seems to corrected now. The action is an casting but for a hard use hunting role I don,t see that as a negative. I,m very pleased with the bbl. it does not seem to collect any copper fouling. I have been going 50 rds. between cleanings same thing for another bbl. I have of there,s in 223rem.
