I will say that in my experience with 222,223, and 222 mag on game coyote sized and larger I notice no difference. I’m sure there’s something to see when using 40s for colony varmints where the added speed adds destruction, but with tougher bullets on bigger stuff they all seem more alike than different to me. I haven’t noticed a marked difference until getting up to the 22-250.

I bought into the 24HCF craze for the .223AI
Performance wise on anything...I couldnt tell the difference between that and a plain vanilla .223
