Testing Percussion Caps

Though dropping the loading lever is common with this model, I tyoically haven't had a problem. Perhaps I am loading it heavier. I had to empty the cylinder before I could load with my homemade percussion caps. These caps are punched out of soda can aluminum. The caps primed with cap gun roll caps were a failure. Caps primed with 'Prime All' are much better but I have a problem seeing how much priming compound I'm loading.
