Joe, one could get 3 hulls out of a foot of the brass. It'd last a lifetime. I looked at the site and saw where there is "cartridge" brass and another type brass alloy, the 360.
The 12" billet of 1.5" would weigh over 6.5 lbs. That's a lot of brass on the floor after making the hulls. Gil
I can't recall where, but I once read about someone who made brass shotgun or bore rifle shells by lathe turning the base section from solid brass round stock, and turning a separate piece of appropriate diameter brass tubing for the case hull. Then the hull section was soldered to the base to make a complete shotgun shell. Has anyone else ever heard of this? It would seem to be a viable method that would involve a lot less machining time, waste, and overall cost.
