Helping a friend develop a load for his Colt 20" HBAR which has a 1.5 power Compact ACOG. The reticle is the red +. Distance is 100 yards to start. Today I was able to group IMI 193 into 3". A load I had put together using the Hornady 75 gr HPBT Match and H4895 for my 16" RRA M4gery, put 5 shots into 1.25".
Am I realistically going to be able to do much better than 1.25" with such a low power scope?
