When I started shooting flintlocks I was told to tilt the pan to the right to move the prime away from the flash hole so it wouldn't act as a fuse . So I have always done so , that is until I looked at this ;
Bill Knight | BlackPowderMag.com you have to go back again and again to get all the pages .
Now I prick the flash hole further in than I used to then I prime 3 grains ffff from a little horn with a valve that drops that amount , my ignition speeds have gone up so much I actually jumped when I fired the first shot , there is no hesitation that either I or the other shooters with me can detect , it is like that saying " fast as a cap rifle" .
There are many here who use their main horn to prime their flintlocks , nothing wrong with that if that is what you want .
I hunt in New Zealand's hard dense southern mountain rain forest which is full of large ferns , fallen trees , creeks and gullies and other tangle foot , which needs to be navigated very carefully , so for safety's sake I am regularly opening my frizzen and dumping the prime powder . I have taught myself to re prime with my little horn without looking at the pan . I could not do that from a large horn .
