I used a 130 gr BT in a 270 win with 22" barrel this year. 59.5 H4831SC gave me 2960 fps at muzzle. Both deer shot behind the shoulder, one at 40 yds, the other around 140 yds. One ran 40 yds, and the other dropped right there without taking a step. Huge exit wound, and the 140 yd shot split into two, one exiting off shoulder and the other through the ribs.
I shot the AB 130gr last year and got very little expansion and switched to BT at the advice of a friend. The deer shot with an AB ran 40 yds after being hit behind the shoulder.
All three of the above were heart shot, so I don't think expansion would have mattered, but AB left very little blood trail so tracking would have been more challenging if it ran a good ways.
The pic is of the deer shot at 40yds, tore a good 5 inch hole in off side ribs.
