Could you use a 5.56 blank for a 22 barrel?

I don't think so. A .22 centerfire uses .224" diameter bullets and a .22 rimfire uses a .222" bullets. Also, the rifling twist would likely be way too fast

Fast twist is what I'm looking for.

My little Glenfield handle subsonics very well with the 1-16 twist, but I suppose some brands may not.
