6mm brx chamber clearance

[Dutchman]

I have on hand about 100 loaded rounds of 6mm BRX Lapua with a loaded neck diameter of .266" (prior gun was a neck turn chamber). I recently replaced my barrel with a "no turn" neck .272" chamber on my gun so now I end up with .006" total clearance in the chamber so my question is am I safe to shoot this ammunition with that much clearance?
Thanks,

Yes, the neck clearance will do nothing to negatively affect much of anything. I've run .010+ in 308's with no ill effect.

Run a search on the site. There was a recent thread on neck clearance. Thoughts on how much is just right have changed over the last several years. Many (myself included) are now running .005" for our match rifles.

Thanks Keith for the come back................I will try and locate the thread you mentioned I just wanted to make sure I wouldn't be separating the neck from the case when I shot them. That's interesting that your running .005" clearance and it's working out for you.

Unless you are annealing every time or at least every other, you will be work hardening by sizing the neck down and expanding to seal the chamber quite a bit.

Watch for split necks and blow back on the neck and shoulder.

Agreed, I'm an annealer - every firing!
