I asking because I have a gasser coming, and while it has a 20" barrel, I'm going to shorten it up to make for a handier, suppressed package. I have seen all kinds of posts about how "155 Scenars need to be pushed fast (2900 fps+) to perform." My personal experience does not agree. I have found that the like to be pushed HARD, but if the barrel is too short to develop crazy velocity, they still shoot. My bolt gun load is 46.5 grains of Varget with a Lapua case, it makes 2800 fps and shoots a consistent half moa. I make good hits out to a thousand yards, out performing a buddies 26" barreled .308 (TRG-22) that shoots 175 SMK's at 2650 fps (in drop, drift, and hit percentage as a result of both.)
My question is- if you go shorter in barrel, and down in velocity further, does this continue? It seems as though in spite of case length issues and the shorter barrel length I should still be able to get an honest 2700 fps, which with 155 Scenars still makes this a decent long range gun.
Anyone tried it? Seems as though everyone is stuck on 175 SMK's going 2450 fps or so, but this seems to be a better solution, at least on paper!
