Thread update: Got my AR scope a couple of months back and I'm just now getting it sighted in good. I took 20 shots at a range of about 100 yards, using PPU 55 grain BT FMJ 5.56mm rounds (M193). My first couple of shots were off the right side of the paper but I got on target quickly.
I got some that are a little higher than the rest but at present I'm happy with the results. When I get a chance to go to my father-in-laws I'll try my luck at hitting something at a range more than 100 yards.
