To add a little to my response above concerning brass length, I've been shooting my Maximums since around 1985 using only reloads and Remington brass. Bought 500 pieces of brass back then just in case the rumors were true about the brass wearing out quickly and/or stretching thus needing to be trimmed. Most of my brass lasts well past 20 reloads and I have never had to trim the first piece. In fact, compared with new brass the fired brass usually SHORTENS just a little. I've not read about brass growing shorter with use, but my 357 Max sure does. Go figure! Why might this be happening?
