RE: .54 GPR and Pyrodex RS cause slight delay
Finnadict.. I kid you not, I had to get two tins of the Remington caps to hold me over until I could find something else, and I bet I had over 10% misfires out of those tins. The CCI Magnums worked great for me but I did not like the plain CCI's. And the 1075's I can not remember ever having a misfire with them.
