I have a Lyman Great Plains Rifle in .54 flintlock that I use for hunting and recreational shooting. At the bench, she works great, but when hunting I can't even count the number of times that I've looked at my flash pan to double check that it still has powder in it, and it's empty. I do try to hold my rifle horizontally to minimize dumping out the powder from the closed pan, but even still, on many occasions, even when I'm careful, it empties itself out. I can accept a certain amount of this, but in comparison to my brothers' flintlocks, the Lyman seems to do this a lot more than theirs (other brands). Their rifles are consumer grade like my Lyman, so not comparing high-end to consumer-grade. Is there a way to tighten up the lock so that after loading the pan and flipping the frizzen into firing position, the frizzen will "stick" tighter against the pan?
