Not sure if you're interested, but I got out today and put about 400 rounds of the Independence (IMI) M855 through the Mod 2 Carbine, along with about 200 rounds of my usual Wolf Gold. Was a great day and I should be back out there tomorrow doing the same.
Few pics of the dirty SR-15 for those that appreciate them. Not this dirty from today only. Hasn't been cleaned since new, with just about 2500 rounds through it since.
As far as the Independence M855, I saw no signs of the overpressure that many others claim to have seen. No pierced, popped, cratered, or flattened primers, no ejector swipes, no crazy extractor marks, no stretched cases, etc. The stuff ran just as good as I had hoped. Below is a comparison pic showing two Independence cases and two Wolf Gold cases. All four from today. Just as an FYI, all 600 or so rounds were shot through an unsuppressed 14.5" Mod 2 Carbine, with an SR-25 tube, A5H3, Sprinco green spring, and a MAMS.
