Sharps Paper Cartridge

I stock several different lengths that cover most gun-bullet combinations.  To get started we need to determine the length of tube you require.   To do this place a dry bullet of the type you intend to use into the chamber, lightly push it forward and measure from the base of the bullet to the chamber face.   Then I will need to know the ring tail length, if you are using a bullet of this design.  These two dimensions together will be the length required.

My tubes are designed with an internal diameter of .47 inch.   The tube can be flared a little if needed.

Loading the cartridge:

After adding your preferred amount of powder with a card wad the tube may not be full. The air gap is okay, and filler is not recommended.  I would suggest that you glue a card wad over the powder in all cases. The glued in card wad helps the tube break up. These guns are designed to work with less than a full chamber. The best material I have found for the card wad is a 45-caliber disc punched from cereal boxes, or from Circle Fly. This also provides some protection if you knock a bullet off the tube in your cartridge box. No powder spills, making a mess and a potential safety problem. It also keeps the powder tight up against the paper closure for fast consistent ignition.

The bullet tail needs to be clean and dry and is held in place with fingernail polish, DUCO Cement, super glue or white Elmer’s Glue.   Again, there are other adhesives you can use and you need to experiment to find one that you like.   I do not recommend Gorilla Glue, or other products like this.

Once the round is dry, dip lube the bullet to the tube or paint the lube on the bullet with an acid brush. In all cases keep the nose of the bullet clean for best down range results..
