223 AI-Talk To Me

[HOGGHEAD]

I own a couple 223's. And I have pretty good experience with the 223 cartridge. But I have no experience with the 223AI. So fill me in guys. I am looking at a Cooper in 223 AI. I have all the components for the 223, but nothing for the 223AI. Can I use my dies, what new dies will I need to buy?? I have a bunch of factory Black Hills 223 ammo with the 50 grain V-Max. This ammo shoots lights out in my Rock River AR. Can I shoot this in the Cooper AI, and then just neck size the brass?? And still use my standard Forster BR seater die?? Just looking for general information.

I was in the process of ordering a new Cooper in 17 Ackley Bee or possibly a 17 Fireball. But then I ran across a good deal on a left handed Cooper in 223 AI. This cartrige is a little larger than the 17 I want to order. But it will still get the job done. Thanks, Tom.
