The incredibly strong Fast-Load Powder Measure Stand has a rigid frame and extra long arm that lets you fill an entire 50-count Universal Loading Block. Accepts any measure with 7/8"-14 thread. Lock-N-Load Bushings: If you have more than one powder measure, you can switch them in and out of the Fast-Load stand in just seconds, using Lock-N-Load bushings. Long Reach: Lets you bench-mount the powder measure and still drop powder in the loading block.
