As a gunsmith who has built a number of .223 AI rifles over the years, I would advise you to do it if you have a 24" or longer barrel. At that barrel length, you should be able to get about 200 fps more than the standard .223 - which will put you at about 3500 fpswith a 55 grain bullet. I have been able to get almost 3600 (AA 2520 compressed load) with a 26" barrel. I don't normally load a 22-250 much over 3700.

Accuracy should be good when fire forming loads - guns usually like the same loads they liked before it was converted to AI. Brass life is a lot better and you don't have to trim cases again once they are fire formed.

You should know that, mostly due to all the misinformation floating around out there - and the fact that not all gunsmiths know how to headspace the AI calibers, the conversion to AI will not add any value to your rifle. It may actually make it harder to sell down the road if that is a possibility.

The fee to do the conversion should be about$75. Good luck. Roskoe
