[QUOTE="7mmRHB, post: 106288, member: 3584"] JB, how much thickness variation was there from side to side on the necks? Were they thicker at the base than at the mouth? Did the variation show up on the measurements of the loaded rounds measuring completely around the neck? Was the amount of bullet run out effected by the neck wall variation? The best lot of 6br norma brass from Lapua that I have ever match prepped was 5 to 7 ten thousanths fromside to side and more than that from base to mouth. Most lots aren't that good!!! The flash holes are generally to deep to do anything more than just touch the corners anyway. How many brass did you start out with or are you just useing it (as is) without sorting? Sorry to ask so many questions but I'm very interested in the methods you're testing and the corresponding results. I'm assuming you will try some full match prepped brass from the same lot to prove your therory that you don't need to spend all that time prepping brass.---RHB [/QUOTE]
