Would like to make some shotshells for 45LC. The problem is the Ruger New Model Valquero cyclinder is not bored full diameter all the way through. It is like the forcing cone is in the cylinder, not in the frame before the barrel.
With this, I can not simply use a longer brass cartridge, such as a 454 Casull or 460, or even a cut-down 410 hull.
I've heard of fire forming 303 British, but I would have to cut down, trim, etc.
So how can I cut, trim to length, fire form and load the "tapered" casing???
Why....because I can (or want to)
