Its a flintlock. My terminology is what needs some fixin. Anyways, here is the link to see the gun I own.

The owner of the gun shop where I bought my firestorm sold me the pyrodex pellets with the gun. My buddy who was showin me the ins and outs of the gun only shoots triple 7 out of his inline so he assumed they would be better than the pyrodex pellets for mine as well even thought it is a flint.
At the range, I just took his advice on using the 777 vs. the pyrodex but I need to go back today and try some rounds with the pyrodex pellets.
