ah, that could be it. i only have 50 rounds through it. :)
i do have a bunch of lighter bullets (also CHEAPER), so i guess i'll load up 100 or so and run them through the rifle to start getting the upper broken in. it is a completely new upper (new bolt and carrier and everything else). the rifle has a collapsible Rock River Arms stock, and i'm using the buffer and spring that came with the stock.
i have started compiling every bit of reloading data i can find on the 200+ grain bullets, so if i can put it in some sort of sensible spreadsheet, i'll post it here.
