I'd think about how fast I could get a 155 Berger VLD going on top of one of the newer powders like Big Game. That bullet is as slick as several of the non-VLD 165's under consideration.
If I was going after speed goats with an '06, I'd be thinking along those lines. HVLD's expand at non-magnum velocities, are slick in the wind and are efficient killers. Big Game had worked well for me in the '06. Shots can be long and crosswind not uncommon.
