My 14 yo son shot these groups (first 2 @ 100 and last @ 300)at a couple of GH matchs this past summer with his .223AI shooting 75 A-Max at MV of 3,061 fps out of a Brux 28 inch finished HV barrel. Gun is a hammer and he whooped up on the 6PPC and 6BR guys at the match. We are using 24.5 grains of XBR-8208 with Lapua brass and BR-4 primers. He has shot it out to 600 yards but he's still learning how to read the wind. This rifle is just plain fun to shoot and no recoil as it weighs 17 pounds.
I also use 75 A-Max in my 8 twist Swift woodchuck rifle at a MV of 3,550 fps. One heck of a bullet. I am sorting them by weight and then on a Buhay comparator for both rifles.
