I’ve shot 2F in both my flintlock and snaphance, it's a bit too course - I've always thought of it more as cannon powder. Given your piece though, the caliber and payload - it’s totally understandable.
I think most of us here shoot 3F. Except for special cases, I don’t think most of us use wadding during reenactments – makes a mess of the field and can become a potential projectile.
