[QUOTE="grsever, post: 34982, member: 2794"] Here is my experience with the 280ai, i build mine a year ago and opted for the 140's , I used hornady and remington, I started with H-4831 @ 62.5 grns and went up to 64.5 grns that is where primers started to flatten, the hornady 139 SST were by far faster which i contribute to less bearing surface, at 64.5 grns they passed my cronograph at 3425 and the remingtons 140's were at 3350, prudently i backed them off a grain keeping the hornadys at 3375 and the remington a whisker behind them, as always start low and work your way up, btw.. i have a 721 action , shilen # 5 special match grade SS 25 inches long, maga-na ported. Good luck as this is one of the better cartriges around [/QUOTE]
