I've found the 140gr BT to be a good one when velocities are reasonably low. I run them at 2,000-2,100fps in a 7mm-08 youth load and they penetrate pretty well while inflicting good damage. A buddy has used the Federal factory BT loading for years in his 18.5" M7 7mm-08 and they have been outstanding. His MV is likely somewhere around 2,600-2,650fps. I doubt I'd like them as much at 3,000fps+ on close range, tough-angle shots.
