I set my "IDEAL No. 5" Dispenser to throw a charge which will weigh what I have in mind, and, this has been extremely accurate and consistent. I eep the Hopper 2/3rds full or more, also.
I am not loading for BP Long Arms though, only for .38 Special and .45 Colt, so, no need for me to be so fussy, but I just like the idea of consistent to a fine degree charges, merely on principle.
