I took my .54 GPR to the range and tried loading it with 90gr. Pyrodex RS with a CCI #11 cap and a PRB and when I let off the trigger there was a slight delay between the cap being popped and the powder charge going off. Now when I use Goex 2F with everything else the same I experience no delay at all. Is there a way to be able to use Pyrodex without getting a delay? Perhaps I ought to try Pyrodex P instead. It works just fine in my Crockett .32.

Any suggestions would be appreciated.
