Abstract
The adjustable powder measure is designed to effect the reloading of firearm cartridge cases. It comprises a main body in the form of a transparent powder container 6 with a transparent center tube 7 able to slide inside the container and powder contents. Measuring and dispensing is viewed through the transparent components. The friction fit plug 8 is adjusted to obtain the desired volume by insertion of a graduated rod 10 into the bore of the center tube. A reprimed cartridge case 1 is attached to the transparent pliable end tube 2, the powder measure being held vertically with the cartridge case at the top. The center tube is drawn below powder level, filling the measuring cavity above the friction fit plug. The center tube is then pushed through a sealing washer 4. Inverting the powder measure allows only the cavity contents to drop into the cartridge case.
