Bolt action. Barrel no longer than 22". No magnums/AI. Flattest trajectory with 85gr-140gr bullets. Deer killer. What is your choice?
Good criteria. Don't need a magnum to kill deer. Good range of bullet weights. Lots of good choices out there--my choice is 6.5X55, but I settled for a 6.5-08 in a 22" barrel. Plenty of power for deer. Modest weight and recoil.
