Gunster; I got busy and built one of your adapters for my chargemaster combo, but instead of a 222 case for the inside, I used a 220 Swift case. Real snug fit, no epoxy needed, and the perfect solution for a minor irritation. I dispensed 25 consecutive charges of powder without one that was plus .1gr. I'm thrilled with the simple but effective solution. Regards, Eagleye.
