Ringworm did you post in the AR challenge thread? I just posted again with worse results but still with the hand loads I tried the best I could do was 1.4 inches for 20 shots. You should take the challenge and post up your targets.
How's this?
At any distance I'd likely use or need an AR , a better choice would obviously be to retreat to greater position of advantage and use a more suitable platform.
AR's are toys. Big boy erector sets.
