There's also the fact that AI cartridges don't need trimming as often.
As well as being able to pick the low node/lower pressure, and get the same or a little more velocity as the parent case, which extends barrel life, throat life and brass life.
223AI is quite impressive.
So is 20-221AI.
I'm happy with both and what they offer.
Though IMO the short 221 case is better suited to a smaller action vs a standard short action, which is exactly why I went to 223AI in my M700 and why my CZ527 is still in 20-221AI.
If only there was a magazine that would take a 2.63" OACL for 223AI!!!!!!!!!!!!!! Because those 88's at 2800+ fps do very well at longer distances. Which brings me to using the BR case for them for my next project.
I love the 17 Fireball, but mine is in a short action Remington 700. Every time I shoot it, I feel that the action is too big for it and that I would prefer it in my CZ 527.
