Has anyone used a ferrorod as a flint?

Hey friend, I think you’re traveling down two wrong paths.

Good flints are easy to obtain and rust is not your friend.

You got more problems than needing flints.

I'm convinced that ferrocerium can help a wheelock (I've tried it) but I don't think it's a good idea for a flintlock. If you can't get flint, you can get other hard metamorphic stones that'll do the job properly.

Also, from what I've read in the Muzzle Blast magazine, guns that have been soled on the frizzen with the material you are trying to use are not allowed on the range.

What is not allowed is depleted uranium!
