OK, so really you guys are checking the brass length and trimming to the standard or spec you wish to you use, if I am hearing correctly. Hopefully not trimming often but when required.
My brass was all a touch longer than book spec from the beginning. Lapau brass. I was thinking now that it has all been fire formed and reloaded a couple of times I would trim again. Most of the brass, with a few exceptions, is all the same length since the first fire form, which indicates very little growth and a good thing.
Correct me if I am wrong. Thanks guys.
