There's alot of us that have the 280,and most of them call it there go to gun for hunting ( including me). I have not found a load yet that will beat the 150 gr. Rem. Corlokts yet(1 1/4" at 100 yds.) Most of the guy's are using the 140 gr. corlokts,and are very happy with the load. I've tried B.t.'s,Hornady's and Sierra's with IMR 4350 ,Rel. 15,19 and 22 with no improvement in accurcy. If you find a good load for your's be sure and let everyone here know about it. Digger
