The Nosler brass I have bought has been flash hole be-burred, weight batched, chamfered, and trimmed to same length. The only thing you should have to do is run them through a neck sizing die (or just far enough into your regular sizing die), to straighten any neck bent during shipment. They are great brass ....very well prepped. I even checked them for neck thickness uniformity and they were acceptable.
Well after checking my nosler brass, I have decided to throw away all of my winchester brass because..
1: They have been loaded god knows how many times
2: The nosler's really are prepped right. The cases measured 2.003", 2.004", 2.005" and 2.006" but there were multiples of each, not one or 2 of one and a bunch of another.
