As you know, many .455 webley had their cylinders shaved for 45acp and moon clips.
A few years ago there was a fellow selling headspace rings on eBay and other places. The ring alloys use of regular 455 ammo.. Basically it's a spacer.
I bought one many moons ago. Went looking for another now that I am getting a second .455.
Can't find the seller. Anyone know of a source?
Thanks
