Check the listing for details. Lyman #55 Powder Measure Addons. Color: Black, Condition: New. Listed at 20.00 USD. 3D printed drop tube baffle that drops powder directly into the pan, a thrust washer that holds the drum securely to one side, a baffle to regulate pressure on the measured powder, and an extra lid. The Reservoir Baffle is placed in the powder reservoir to eliminate the change of pressure on the measured powder as the amount of powder in the reservoir changes. The Thrust Washer is placed between the cylinder and handle, and applies pressure to the casting to prevent the cylinder from shifting while in motion to insure a more consistent operation. The PowderChute slows the measured powder down to prevent it from splashing out of the pan. The Tubes connect the output of the Lyman #55 powder measure to the PowderChute. The Lid keeps the powder in the reservoir. Thanks for looking.
