I dont have a Sportical, I have an LR-308 AP4 which has a 16" barrel. I only took it to the range once now, a coupla days ago to break it in the DPMS way. I shot about 30 rounds through it when I loaded 10 rounds in mag. I only have a 100 yard range. I wasnt going for accuracy at all but just shot it for proximity using only the iron sights supplied with the gun.
I picked a brown spot on the hillside at 100 yards about the size of a pie plate. Standing off-hand I hit in the brown spot for the 5 shots thrown that way. I then shot 5 shots at 50 yards, half standing with forward elbow resting on pistol bench, slow fired all shots and called 1 flier for rushing the shot. I went down to check the group and 2 shots were tearing the X and 2 shots were inside the X Ring. 5th shot was 3 inches out of X Ring. Its a keeper!!! Dont care for trigger though and will upgrade this summer along with EOTEC Holo sight.
