Mine has the more sporter-ish stock and the shorter 1:9" twist sporter weight barrel. It likes my 69gr handloads but doesn't shoot my 75gr handloads near as well. I will be testing it with XM-855 62gr Federals, which I expect should shoot fairly well in this barrel, and spare pelts. I intend this rifle for short and medium range hunter-like applications. It's not quite up to shooting to match spec accuracy, but does quite well for things like hunting. I have only had it out for a couple of 250yd range outings so far, but it seems to operate flawlessly with a fairly wide variety of 10rd (this is New York, sports fans...) magazines.
