Those groups were right at 2,900, and I got up to just over 3,000 at the top end with good accuracy.
Smokey - that sounds pretty good to me w/o hot rodding.
I know the 270 Win will push 150 grs @ 2900 safely.
For the 280 AI and 150s --3000 fps does NOT sound out of reason.
Good luck with the draw and hunting.

FWIW - I know there's a diff in SD & BC between
270--150s
and
284--150s -esp. Scenars.
