These are the 2 bullets I am using in my 280AI’s.....getting a bit over 3200 FPS with the 139 LRX and about 3175 with the 145 with RL26....and very accurate. I use Quickload Software to work up my loads and confirm with Oehler ChronographYes, I reload. In a light 7, I’m looking at the Barnes 139 or 145 LRX.
