You guys count?? I just shoot away until it doesn’t work and I can’t get it to work anymore.
I'm probably a bit OCD but I keep a log of all my shots. I have a notebook that I take to the range and log which rifle, how many shots, what granulation and how many grains, which flint, and when each flint was changed. I also track misfires and pan flashes. When I get home I transfer all that info into a spreadsheet which makes it real easy to look up how many shots I got with each flint, among other things.
I'm retired and my wife is dead so I have lots of time and I've always enjoyed working with numbers.
I guess I'm just cheap but I squeeze every shot out of a flint before it's discarded. I shoot till I have two misfires in a row, then knap if there is still enough flint left to do so. It's only when the flint becomes too short that it is thrown out.I think a lot of guys exaggerate their claims on number of shots from a flint. That said, I've had a couple where I got a couple dozen shots out of them before they wore out. Normally about 20 max and it becomes part of the landscape again. I don't even attempt to knap them. To me it's like trying to reuse a napkin..
Because I keep detailed records I know for a fact how many shots I got on every flint I've used. You may think I'm a liar but my personal record for shots from one flint is 169 on a french amber using my trapper pistol, which for whatever reason is really easy on flints. My best for a rifle is 150 shots with a french amber using a deerhunter. Without counting up to get an exact number I'd say the five flintlocks I own average about 50-60 shots before the flint is done.
