[QUOTE="DoneNOut, post: 2808809, member: 113404"] I got a 137HH to 3020fps 20" 308 AR10 with adjustable gas block. Spits the brass straight 90 from the ejection port. Runs like a well oiled hammer! LOL Yes, loaded to 2.760, or crimped in the first groove below the ogive. They have a .090 ish jump. I used 49.5gr AA2520. Shoots bug holes. Like .05 MOA. [/QUOTE]
