Did you have to duplex that load? The reason I ask is, I was shooting the GPH today. I had saw your post earlier and decided I wanted to see if this GPH would fire off APP 2f. So I loaded 80 grains of it and a patched ball. I did not really care where it would hit. I primed the pan and went through two pans of prime and still no ignition. So on the third prime, I stuck the priming flask against the touch hole and pushed, then pulled that out away from the touch hole. That time it went off, but there was a definite tick..... BOOM. I then duplexed the next load with Goex 2f first and it went off much better that time.
