7MM 08 40' Improved

[Larryjk]

Ridge Runner, I agree with most of what you said, except you were 100% wrong on polishing the chamber. If a reamer is sharp, you will get the best finish in a chamber relative to what happens in there when yu pull the trigger. You absolutely do not want a glassy, shiny chamber. Then the pressures have to be peaked before the case expands enough to grasp the chamber walls. The case has been pushing back against the bolt face, and in turn the lugs with all of the chamber thrust of the case. Don't get the chamber too smooth and you will be doing your gun a favor. If you polish, no smoother than about 220 grit cloth.
