Yea, your probably right. I have been shooting no. 11 regular caps on my musket
Since 1972 and never had a problem. But what do I know. Here is a picture
I took of a regular CCI no. 11 cap being fired. If this won't fire your musket,
You got a problem. As far as fidleing with them with your fingers, ever hear
Of a device called a capper? Wonder how the boys cap. Their revolvers?
