22 ARC or 6ARC

I believe Colorado, Connecticut, Illinois, Iowa, Massachusetts, Virginia, Ohio, New Jersey, Washington, and West Virgin. There could be more or less on that list.

Which states is it currently “illegal”? Is there a confirmed list somewhere?

Wyoming for starters.

6mm ARC. Legal in all 50 states, light recoiling, cheap enough to shoot a lot.
