I usually shoot FF in my flinter, but I'm almost out, and am heading to the store to pick up another can before I do the yearly pre season check up/range trip. Is there that much difference between FF and FFF? I hear some guys say FFF gives qicker ignition than FF. Also, in a pinch I could use FFF in the pan, if I forget/lose my normal FFFF in my primer. So, stick with the FF or go for the FFF?
