What flints do you use?
 

After using several different flints, I'm finding out that my flintlock likes Rich pierce flints and tom fuller gray English flints. I can usually get around 10 shots with RP flints before I have to sharpen them and I get around 6 or 7 shots with the gray English flints before I have to sharpen those. What flints do some of you guys use and how many shots can you get before you have to sharpen your flints?

It depends what you prefer
 

I have been using Old English or German flints from a local gun shop. They seem to work well and I replace them after they fail to give good ignition. Never counted the shots I get from these flints, but it seems that the ones you are using should last a bit longer. I never learned how to sharpen or knap flints so I just buy new ones. All the best...
