First off let me say I like your selection of calibers!! As far as factory ammo goes it's all I use cause I don't reload either,that may change in the near future.

You know you're gonna get the standard answer "let the gun tell you what it likes" and IMO a good answer. With that said I've never used a premium bullet on whitetails all my deer were killed with Rem. core-lokts or with Win. super-x.
