Belding & Mull powder measure. Reason for selling: Replaced by RCBS Chargemaster. Pretty fair condition operating wise. Top cover is missing, been gone for years. Glass is cracked, a typical problem with these units but only if that kind of thing bugs ya. /ubbthreads/images/graemlins/frown.gif Regular size charge tube, not magnum. Works great when set up properly. Never weighed charges when shooting 222 or 270 after proper charge tube setup. 50 bucks gets it shipped to you.
