I was looking at my brass today. I noticed that starting out with factory ammo, in this case Hornady TAP and FEDERAL Match, the overall case length was 2.005. When I measured the once fired brass I got two different measurements. The FEDERAL brass measured at 2.019 and the TAP at 2.015. Both cartridges were new factory ammo, fired out of my SAI Socom II. Is it normal for the brass to stretch this much? My other question is, based on SAAMI guidelines and the size of all of my factory ammo, as long as I make sure all of my reloads are 2.005 I should be fine right? Here are some pics.
