I just bought a .54/28 ga smooth bore fusil D flinter and do not have any wads/overshot cards. No where local to buy them so I either have to wait to shoot it with shot or substitute something of for them. I have heard of the old timers using wasp nests but since I don't have any of those either what can I use? I have never fired a smooth bore with ball much less with shot so I need educating.ThanksDennis
