[QUOTE="Mysticplayer, post: 34798, member: 8947"] The neck tension of 4 thou is plenty. If you can't wiggle the seated bullets by hand, good to go. This is a match rifle so the ammo will not see any abuse. I prefer to have 2 thou of clearance from the loaded neck to the chamber wall. Others have used less but I am a chicken that way. I bet your ability to measure is to around 2 thou error, maybe more. Recheck all measurements with a guage that can measure to within 1/2 thou. With clearances this tight, you just have to know. When you fire the ammo, the case necks should still show soot. however, the necks will not need sizing ie bullet doesn't slip into neck. if there is no clearance between neck and chamber, you can run into some pretty scary pressures - kaboom. So please be careful. Keep the chamber neck area clean and polish the necks of the fired cases with steel wool. Just about any dirt is going to take up the little clearance you have and pressures/accuracy will be bad. Match chambers are wonderfully finicky creatures. Shoot safe... Jerry [/QUOTE]
