After shooting only XM-193 and Wolf out of my 3 AR's. And keeping my last 4000 rounds of XM-193 in reserve since it's getting hard to find, I decided to try the Green Tip & AE223 55gr.
I took out my 20" RRA 1:9 twist and was amazed how tight the group of green tip was at 50 yards, less than 2 inches. The AE223 was all over the place 6". I thought the AE223 was good stuff!
Now it's time to try the green tip in my 1:9 16" carbine, and guess I will keep the other AE for my 1:12 M-16 Clone.
