Tres, I'm sure there are MANY people on this forum much more knowledgeable than I, but I can give you MY experience w/ a 7RM.
I never, in over 2000 rounds thru my old gun FL size until I could no longer close the bolt without a LOT of difficulty. This, being a hunting rifle as well. If I didn't have to struggle a lot with closing the bolt, I continued to neck only until I did. (fyi, i ran EVERY round thru the mag/chamber BEFORE a hunting trip to weed out those that needed FL sizing).
The number of reloads varied, but I couldn't tell you EXACTLY how many, because back then, I didn't keep real good records of how many time a brass was fired. My sense was that it was at least 5-6 times. Of course that would depend on a lot of things like how hot ya run it, etc. and I trimmed regularly.
When it got too hard to close the bolt, I FL sized 'em & kept on shooting. I shot out the first 2.5" of my bbl. and THAT'S what prompted this new 7mm/300WM build on a 7RM take off bbl. I bought.
btw....thanks again for all the great reloading info on your write ups. I'm learning a LOT from all you guys on this board!

What is barrel life like? What kind of round count could a look for in a match rifle?
And are you guys saying you neck only size your belted cases? I have had EVERYONE tell me to always FL size belted cases..... Sierra Bullet techs, Sinclair International techs, etc.
