I've begun my AR22 build. I'm about to settle on a dedicated 22lr barrel, but today I hesitate. I'd also like to upgrade a 5.56 barrel I have. It's a 1:9. The dedicated 22s, are 1:16. Is there a noticeable difference between the performance of the two on 22 bullets. If I could kill both of the proverbial birds with a single Noveske stone, I'd like to.
