[QUOTE="D.P., post: 96862, member: 2541"] I don't know the exact specs, a loaded cartridge (no neck turn Norma brass) is .339 so on the 340 neck thats only a half thou all the way around too tight. I believe my neck is about .343 that's 2-thou clearance all around. For a hunting rifle it's about perfect. It shoots sub 1/2 MOA most groups being 1/4 MOA. The first time on paper at 1K it went 6 inch for five shots with four shots at 2.25" I was happy to have JB as a witness. Heavy Broughton Barrel on a 700 action Sako Mcmillan stock Built by Chris Matthews LongShot Rifles. [/QUOTE]
