Just ordered my first barrel from Stockade Stocks in 6mmBr which is being installed on a Savage action. I asked for a no-turn neck and was told theirs was .271. I made up some dummy rounds with Lapua brass and 75g V-Max bullets. They measured .2694 at the neck. Is this enough clearance or do I need to do alittle neck turning. Up to this point in my reloading I have never had to do any neck turning.
