I have been developing a load for my 260 using fired Lapua brass recently. My standard process is to use a body die to bump the shoulder. 002, then neck size with a bushing die (if loaded round neck OD is .294, I'll use a .292 bushing). I've had pretty good results with about .00005-.001 runout. I intend on using these rounds for LR shooting and matches. I've just about dialed in the load and have 300 new pieces of Lapua brass that I want to mass produce it with. However, I have concerns of how I should prep the brass because the neck tension is undoubtedly going to be greater than I typically use. And I'm pretty sure the shoulder has been pushed back further than I use as well. What is the most efficient way to address these issues or is it not worth worrying about? Thanks in advance.
