I've heard lately, actually always, but often recently, talk about converting percussion guns to flintlock. I suppose partly because caps being in short supply and getting more expensive. I own 20-25 muzzleloading rifles, all RH, as well as a few revolvers. Only one of my rifles is a flintlock, a Traditions .50 caliber. I have few precut flints for it and a chunk of flint about twice the size of a softball. I have never tried knapping any flints from the big chunk, not wanting to be wasteful. Sometimes when I learn how, watching a few more videos I will give it a go. Meantime, I would consider converting some of my other rifles to flint. Some I would probably be reluctant to convert are my Thompson Centers. Others I might are CVAs and other brands. I will watch for flintlock locks that can be made to fit where typical reproduction percussion lock were used.
