I like Lake City brass and I am willing to work it until it fits my needs. I have noticed that the lengths vary, sometimes by a large amount just like Stevered describes. I do sort mine by length. The short stuff goes into my bolt actions (1.754 and shorter) and the longer stuff I use for semi automatics. The longest I trim is to 1.765. But most of it falls into the 17.55 and 1.760 range. Yes, this means measuring it with a set of calipers and bagging the different lengths and trimming it to the length I want. But, it's good brass and it's worth the extra work.
