Well then, I have a question. I charge my pan with a brass devise made by Thompson Center that holds a quantity, about 30 + charges, of prime. The devise has a retractible point that when depressed on the pan deposits, by virtue of good old gravity, a small charge of 4F. Should I be using a different method? If so - what? What advantage, in terms of safety, would a powder horn have over what I am using now?
imho- insert disclaimer here, and only in my experience, bla bla bla... i use essentially the same gadget, and i'm confident that i won't blow myself (or anyone else) to kingdomcome, for a the following reason:
what sets off the powder (when you pour into a barrel from the horn directly) is an ember lodged somewhere in the rifling or the base of the tube. once the BP hits the ember, it ignites and then sets off the powder in the horn. if there's not the ember hiding somewhere in the works, you get away with this idiocy, but just that one time.
since you aren't pouring the priming charge into a space which you cannot see, a bit of ember would be easily detected. also, most people blow or wipe the smoke away which would thereby remove the ember. additionally, since the pan is open to the air (and the bottom of the barrel, as a practical matter, is not) there is virtually no chance that partially burned material would be present in or around the pan.
i always prime with the muzzle "up and down- range" so in the highly unlikely chance that something does go wrong, nobody is accidentially shot.
if you are really worried about a flashback from the pan igniting your priming horn (the T/C guy is brass, if i remember correctly, but anyway...) you might want to put a pinch of prining powder in your fingers and put that into the pan, but i suspect you'd be wasting a good worry.
good luck, keep shooting, and don't worry too much
