Had a bunch of folks request some powder tube inserts for the Chargemaster. Tested with Varget and H1000, slightly slower with much greater accuracy. Went from almost 25% slight overcharge rate to essentially 0%..it happened once when I bumped the bench on accident.
Comes in a pack of 3 at slightly different scaling to account for Chargemaster powder tube ID variation. Made from an anti-static PETG polymer, which is very similar to what a soda bottle is made from.
As a bonus, had some folks take measurements of the Chargemaster Lite and Hornady Auto Charge powder tube, and it appears these will fit no problems!
