[QUOTE="riverrat13, post: 1492471, member: 100921"] I am in the market to build my next hunting rifle. It will primarily be used on whitetail. However I would like to have the ability to use it on mulies and elk. After alot of research, the 280 AI seems to be the caliber that checks the most boxes. With 140 grains at 3200 FPS and 180 grains at 2800+, it seems to be able to bring the speed and KE needed without stepping up to a magnum round, while still maintaining decent barrel life (2500+ rounds). Before I pull the trigger, I wanted to get some first hand opinions on the 280 AI and how it compares to relatively similar calibers. (7mm-08, 270, 280 Rem, 7mm Rem Mag) Also, what twist would you recommend, 1:8 or 1:7.5? I will probably stay with the 160+ grain bullets. - I reload, and Nosler Brass seems to be easy enough to get. Worst case, you have to fireform 280 Rem. So I am not worried about availability of factory ammo. - I want to stay under 8lbs bare rifle. So the shorter barrel the better (I am talking 22'' or 24''). That may steer me to the 7.5 twist. [/QUOTE]
