Has anyone tried to make caps using the Tap O Cap device and 32 ga. copper sheeting. I made 50 caps using aluminum soda pop can material and the primer mixture from Sharpshooters .22 LR reloading kit. The caps work well but the aluminum is not durable enough and it blows the center out of everyone of them on a Seneca .36 caliber rifle, using 35 grains of Pyrodex P and patched round ball.
