Home Forums Hunting & Shooting AR and Tactical Rifles Which AR15 caliber should I choose for deer hunting?

I've run 60kpsi IE top pressure loads in 223 in the AR from appx 1986 through 2003 to the tune of between 8 and 20K rounds a year.

Probably more on th average of 58kpsi or so comparatively speaking.

Haven't hurt a thing to this point in time.

Just FYI. No guarantees, as they say, YMMV.

Can't stand .277 caliber so thats out for me....
