My 223AI with a 26" and 1/8tw isn't far behind the standard 22-250 in velocity, and when I use the 75Amax/ELD, it is a potent round on yotes at longer ranges. I am pushing the 75's @ 3,005 using AA2520, so it still carries plenty at 500. Of course my 22-250 with a 1/9tw is running the same 75 @ 3,300 with 4831, but with more powder and not really that much more impact on a yote.
As for P-dog shooting, the 223AI dominates with the higher shot volume ability, longer throat life and cooler barrel per same # of rounds.
