I have a Firestorm and am having much trouble trying to get a good spark. I have English, German and TC Agate flints. I had trouble last season and finally purchased a new frizzen (at a local sports shop) that was hardened at a local heat treat shop. After installing, it seemed a little better and after a season ending cleaning, I put the gun away for the year. However, I shot it (and misfired) this morning and my troubles with spark were "re-ignited". I am not sure what to do at this point. Advise would be greatly appreciated.
