That seems like a very long time to wait on an order.
Here are some photos of no 11 caps I made from beer can aluminum. The first one is the cup after it comes out of the die. My die is an old one from Forester Products called a Tap O Cap, I have had for about 30 years. They no longer make it. The second one is 5 caps that were fired on my Remington new model Army .36 cal. using a large rifle primer cup as dipper. I just soldered a cup on to a piece of copper wire. Dumped the charge in the cup and packed with a 1/8 inch skewer stick. The third one is 5 cups fired on the same revolver, however this time I filled the cups level with the compound and then packed it with that skewer stick. It helps to hold the cup in a pair of archery nock pliers, or you can take an old pair of needle nose pliers and drill a corresponding size hole just deep enough to let the cup set in. The EPH20 mix I am using is safe to pack like this. After packing you add one drop of 50/50 water 70 isopropyl alcohol mix to the cup to activate the mixture. This has to dry for a while or be dried. The 4 part mix from .22 LR Reloader is called H48 and is explosive when mixed so I do not recommend packing it at all, they tell you to add a drop of acetone and let that dry.
Dixie sells them too.
