My Ruger Predator. 223 with an 8T loves them. They are the heaviest bullet I've tried so far and easily shoot into .5" with both AA2200 and CFE223. Not a lot of time spent with them so far and I am limited to the maximum 2.24" or so COAL due to the AR style magazine.Any love for the Hornady .224, 68 grain HPBT Match. I have a Savage 12-BVSS which uses a 9T. These will be paper punchers. Thanks guys.
