For VA whitetails just about any decent 150 to 165gr. bullet will do, including the Rem. Core-Lokts. IMO, no real need for premium ammo for the deer around here. However, the main thing is to just try some different loads, and see what shoots best in your particular rifle.
I've had good luck with Remington Core-Lokts, Federal Classic or PowerShok ammo, Winchester Power Point, Hornady ammo, and Black Hills ammo. My Sako, a 308Win., seems to prefer the
Federal and Black Hills stuff, in 150gr. bullet weights.
My Remington 700, a 270Win., likes anything I throw in it so far.

The main thing is to just try out different loads, and see what YOUR rifle likes best. That's part of the fun of a new rifle too - sort of getting acquainted
