Home Forums Hunting & Shooting Hunting Rifles What does 223AI mean?

Only negative I can think of is up-front cost. Dies are usually pricier. Add to that the cost of AI'ing a standard chamber, which is obviously nil if going the custom route.....which I do.

Anybody that says fireforming is an added cost don't know what they're talking about. You can kill stuff while fireforming. No need to waste even 1 bullet. I sometimes go the Bullseye/COW route in my garage to form a few.....just to get things going.
