If one doesn't have access to hand loads, which I don't currently, and you were going to check out a rifle to try to find factory ammo that it liked best which 3-4 loads would you grab first? My plan is to basically buy 1 box of each and run them through the rifle. Assume the rifle is a modern semi-auto such as a LWRC REPR, POF-USA P308, or GAP-10. Appreciate the assistance.
