I was trying to have an intelligent conversation on reaming a cylinder when I realized that I don't know what an important part/feature is called. I tried to look it up to no avail. It is the little lip that meets up with the cartridge in a revolver cylinder. It is the thing that is spaced particularly to control what length of cartridge you can put into the cylinder, stopping people from loading a .357 magnum round in a .38 special chamber for instance.

I think that this is the thing that is either moved up or eliminated when a cylinder is reamed to accept longer cartridges. (I'm not sure which though would love to know!)

Thanks again for furthering firearms education!
