My most accurate would be a toss up between a DPMS panther and a browning eurobolt with bossCR. The browning is factory original and I got it at a real good deal from a retail store I was working at adn will easily shoot under 1" at 100 yards, generally its in there under .75" with federal premium 100gr SPBT .243 ammo. My DPMS is the 24" heavy bull barrel, with all the bells and whistels, lots of money sunk into it was a thumbhole wood and 6-24 B&L elite 3200 scope on it. It will shoot good handloads into .75-1" groups at 200 yards for 5 shot groups and on a real calm day will shoot in the 3.5-4" range for 5 shots at 400 yards but average is in the 4.5-5.5" range. I can shoot out the center of a clay pigeon almost every time. This is off concrete rest with bull bag, barely touching the gun.
