[QUOTE="Alex Wheeler, post: 1719049, member: 101859"] I did not read all the posts in this thread but here is what you need to know about sizing. Measure the shoulder diameter before and after sizing, same with the widest point above the extractor groove. I like to see .002-.003" reduction in shoulder diameter and about .001" in base diameter. Bump the shoulder back .002" or so and you will never wear out a piece of brass, EVER. You need a comparator to measure the shoulder bump. This holds true for small 6mm cases in 1000yd Benchrest rifles through 338 lapua improved cases. Top accuracy and case life. [/QUOTE]
