Funny. Looking back at years of chronograph notes, I see a general pattern with about a 30-35fps increase in most strings as well.
The first round is usually, but not always, about 30-35fps slower than the rest of the string.
Kyle Lamb recommends aggressively charging the AR15 like a sling shot for the first round, from a bolt-closed starting point with a fresh mag.
