I have often wondered about the acurracy of these due to the bullet diameter being smaller in a 22 rimfire - what's the actual bore size for the 22 HP?
There was one of these 22 adapters listed on AuctionArms for well over a year at $50.00, I see it's gone now - it was listed before one was listed and sold on GunBroker for more - it was sold by a friend of mine who found it in a box of odd's & end's at Tulsa.
