As I'm trying to elevate my game, I've come across another aspect of brass prep where I have a few questions. Turn necks or ream? Why perform one operation vs the other? and when to choose one over the other? What are the pitfalls to each process? I've searched the recent threads and have read the articles here on LRH but I don't see much on reaming the neck. Thus far I've turned necks to simply make each case with even wall thickness' by determining the thinnest point and turning almost to that thickness - about 90% of the neck turned. Doing this has made a noticable difference in the consistancy of groups. A recent batch of 20 carefully reloaded .223 fired through a chrono had an ES of 12. When I threw out the high and low shots, that ES was down to 9. This is the best I've ever been able to produce. Anyone have experience reaming necks?
