What is the proper way to cast a chamber?
The way I do it is:
From the muzzle plug the bore with a cleaning patch.
Push the patch towards the chamber.
I stop the patch about an inch from the front of the chamber. This way I can mic the grooves and measure the throat.
I have my bench vice set up so I can clamp the barreled action with the muzzle pointed straight at the floor.
I leave the cleaning rod in the barrel, against the plug, with either the other end on the floor or blocked up from the floor to support the plug.
I then take molten Cero-Safe and fill the chamber.
Wait for it to cool and push out.
I would recommend against using anything other than Cero-Safe. Cero-Safe melts at a little over 200 degrees and if for some reason you can't get the plug out (badly pitted, jugged or ringed chamber or bore) you can melt it out with a heat gun and not run the risk of damaging the metal from over heating.
