At our local range yesterday I was talking with one of the regulars who, apart from a number of other talents, happens to be a gunsmith/machinist with a fixation on quality.
He related to me that the best sizing die to use for a particular .308 rifle that he owned was a .311! He said that while he had sizing dies in .309, .310, and .312 as well, the .311 was the one that gave the best accuracy. This is not a situation where the barrel was old and worn out or anything like that, it was a high quality match grade aftermarket barrel in very good condition.
I'm thinking that a guy has to "slug" his barrel and then compare accuracy for bullets sized .001. .002 and even .003 over the bore size to see what works best for that particular barrel.
