I recently bought a Browning A bolt synthetic stalker(22" barrel) in 280 and am considering carrying it this fall for a Wyoming mule deer hunt. The rifle is shooting 1/2 to 1" with several powders and the 140gr Ballistic tip bullet, but not at the velocity I hoped for. All my loads so far have fallen between 2710 and 2875fps. I had hoped to get 2900-3000 with this bullet. I suspect that the loading books are cautious with their data for the 280 since it was introduced in the pump/auto rifles first, and I know an extra 2" of barrel would help. Anyone have a pet load I could work up to that would add a few fps?
