Hey Greg,

Hows it going?

You will get miss fires occausionally from those agats. I've seen it happen at the range last year. Some guy next to me was having that same trouble. I wasn't. Told him where to go and get the same ones I have. I even gave him one that I wasn't using anymore. I won't say that you will never have a miss fire, but the chances go way down.

I find that the English flints will last a while. I use the same one up until hunting season, after Christmas. But before than, I will switch to a new flint. Shoot the season with that one and continue next year, unless it gives me a problem. It's pretty easy to remove the old flint and put on another, just wrap the end in the holder with a piece of leather. During the next few months, when I visit a hunting sore, I will pick up a new set, put them in my stuff box and switch over before the season starts.

Good luck...

Tom
