It's a mindset. We don't use percussion or flintlocks because they are better. It's the challenge. We use them to make us better. Better sportsmen, better hunters, better able to understand how hard it was for those who didn't have a Mauser to fall back on and a miss or missfire might mean hunger. And I don't mean "better" to be that were are better than someone using a regular centerfire. I mean the challenge will make us better by making us learn about our strengths and weaknesses if we are to succeed. I might not be better than so-and-so, but I'm better than I was before. That's all that counts. I don't do it to change how anyone else thinks about me. I do it to make me think about me and the deer - or whatever game. How do I get in range of a buck while he gives me a standing broadside? Better - as in better figure it out or go hungry. Or at least go without venison.
I hunt with a recurve bow and that makes the flintlock seem much easier by comparison - though this year I'm eating "off the bow" because I arrowed one in early archery and later passed on a few antlerless that turned out to be the only game I saw in range through regular and m/l season.
Good news is the rifle went right off when I discharged it before heading in after the last sunset of the season and I centered the flat rock I targeted. So it coulda-been if my luck or skills were better. And that, in my mind, was a minor victory and a good season ender.
Suffering makes man think. Thought makes man wise. Wisdom makes life endurable.
