One of my absolute favorite discussions:
Personally I would use either, whether the scenario be small to large game hunting or a survival situation.
However, whenever I introduce this topic to some gun loving friends of mine, I always get the same debate. IGNITION Noone ever disputes that the functionality and performance of either. However I have noticed there isn't many who straddle the fence, one is either a percussion enthusiast or a flintlock lover.
percussion offers a fast re-prime and minimal smoke to interfere with your shot and on this point alone I often chose percussion when I was a beginning BP hunter. Nowadays that I have built confidence in my shot placement I almost invariably choose a flintlock, 1500 shots from 1lb of fffg is more cost effective than 100 caps @ 4.50 a can. Even on a misty humid fall morning a well maintained flinter can and will function aswelll as a percussion rifle. I have found the lighter (color) the flint the harder the stone and often times I can get as many as 50 fires before replacing the flint. But truth be told it really comes down to which rifle I favor for the task!
Love to hear some of yall's opinion on this topic!
