I don't see a separate powder measure in your pics.
Never load directly from the flask into a muzzle gun.
I have 2. 1 for pistol & 1 for rifle. (not pictured).
I swab with wet/dry patches between every shot so there is no danger of that.
Thanks for watching my back though...
Black Powder: Not because it is easy, but because it is hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win...
