I have an AR-15.450BUSHMASTER for short range rifle, compliant with Ohio deer hunting regs. Ohio requires a straight wall cartridge (or tapered) from .357-.50 call.
However, I will, at some point, have a second upper for longer range shooting. Of the available chamberings for a AR-15, what would you recommend? Not looking for specific brands, but best overall choice from a practically standpoint, costs, availability,
My first thought, was just the standard 5.56, but is there a better choice?
Your opinions please.
Edit: I should also state, that mags should be the same standard size, such as the 5.56
(A standard mag with a different follower, is a 10 rd. .450 Bushmaster mag as a single stack.)

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.
