I like the idea of carrying pre-measured powder charges in the field but I did not want to carry plastic in my possibles bag. So I started looking around in the scrap heap I call a shop and came up with these. 1/2" OD copper tubing and 3/4" oak dowel make nice little speed loaders. These are cut to length to measure 70 grs. of FFG but of course the length is up to you. I used a 1/2" Forstner bit to bore out the dowel and the tubing slips in with a nice fit.
