The bore has been slugged at .4508 with a bit of thread choke. The cylinders are in shipment back from DougGuy after being honed and the ACP cyl having the chambers cleaned up. The chambers were really rough toward the headspace shoulder. Heavily ringed. He said since it worked with factory ball ammo he doubted Ruger would warranty it. Chamber reamer cleaned most of it out. I'm looking forward to getting this project in gear.
