You could still buy low brass paper shells in the '60s but loaded with smokeless powder. You can load plastic hulls with BP using 80 grains of 2Fas a 3 dram load or RS Pyrodexand they work fine. This way you can reload with regular wad and shot and not have to buy smokeless powder. I have an article in a coming issue of Backswoodsman Magazine(probably July/August ) on making a shotshell reloading setup for about a dollar. If you use the same components as a BP shotgun load you are home free and on the cheap. I've reloaded a lot of the hulls 10-15 times and they are fine.
