These are my low tech chargers.
The top one has a divider in the center and holds shot and powder. Made from brass tubing and friction fit caps.
The 4 at an angle are brass tubing without a divider and are for either powder or shot.
The two bottom ones are river cane with a natural divider, so they hold shot and powder with with cork stoppers.
I really liked the chargers in the other thread and so I made a version that wouldn't hurt my poor old brain. I made the powder chargers that are at an angle years ago. A word of advise grease the small ends if your going to put powder in them. It won't migrate to the powder. But the powder will oxidize the brass. I used to have 6 of the powder chargers. Could not get the tops off after corrosion.
