This is one my bro re=-stocked for a friend, and I put on the .22 CZ Hornet barrel, rechambered using my .17AckHornet reamer, to .22 Ackley Hornet. bottom picture: .22 hornet, was necked up to .6mm, then down to hold the .22 bullet again, with the shoulder in the right location for positive headspace.
