If you don't know someone with one, you rent a .223 finish reamer for around $36.00 plus shipping. You'll need a .223 go gauge also. There's plenty of how-to tutorials and videos out there.

The only caveat doesn't pertain to to the chamber. It's the rifling in the barrel. Often, a .222 is intended for shorter, lighter bullets up to 55gr and by virtue of that, they often come with a slower twist than a .223. If you try to shoot longer, heavier bullets that a fast twist .223 barrel does well with, they may not stabilize adequately. It's not unusual to find .222 barrels with a 1:14 twist. That's too slow for the longer, heavier bullets. IE, if you intend to shoot surplus XM855 ammo, they may not stabilize as well as XM193.

Not to hijack the thread, I have a rem 788 that was 222, that my dad had reamed to 223 back in the early 80's and Hoot is right, anything over 55 gr doesn't group very well. 45-55 gr. it shoots ragged holes at 100. It has the 1 in 14 twist. Doesn't help we had to cut four inches off the end of the barrel... got slammed in a pickup door.
