This drop tube will make the paper envelope, skin cartridge bag or brass case fill more compacted. It eliminates the tapping on the work bench of the item to be filled. The alignment tray and drop tube are adjustable for different size cartridges. At the bottom of the tube there is a washer that acts like a lid to keep the powder from splashing out. On the rear of the lever there is a pocket to add counter weights for different size cartridges.
