For shooters using them, how do you see the accuracy of the 223 in a production bolt action or single shot rifle?

For many years I reloaded and fired a 222 Rem in a 700 ADL that I bought used for not much with some barrel erosion. Beaten and skinny barreled though it was, it shot under .75 MOA no matter what ammo I fed through it. As the sporting arm aged, I finally sold it off but the 223 by then had taken over the market. Unless I find one used or want to go to a very pricy rifle, the 222 looks unavailable.

Ultimately I would be looking for dime sized groups at a 100. Your thoughts? Are any of you getting this out of a 223 or should I be saving my sheckles for a bench rifle?
