The trash can design is what I got from the Wis. guy wish I could remember his name, (Kaboskey I think), nice guy, very prompt on service. I was surprised though with the amount of powder needed. It is much less than I had imagined. 45 grains of Fg seems to be a very accurate load in mine. I spoke to the owner at Shiloh, way back when I ordered it and he said his son shot his without any case, just loaded the bullet into the breech and dumped loose powder behind it. I tried that but it was, or I was ,too messy. I guess your suppossed to take the breech plate apart to clean it. Charlie was also a great help when I was trying to learn to shoot it. damn now I have to get it out. Wish Ill. would allow us to use it deer hunting. I got yhe foldable front sight on it and a tang for the rear. I believe I got set triggers too. It's a nice set up when I took it to the range everyone had to look at it.
