243 rifle powder charge
Quote from Reloader on May 8, 2014, 8:30 pmI'm building 243 and the power charge changes every pull does not stay with in spec. Press is using rifle charge bar. I'm using IMR 4350 powder. Anyone help would be greatly appreciated.

It helps to slow your downstroke speed, so it takes at least one full second to move the powder bar from one side to another. Some customers have taped an aquarium pump to the hopper to vibrate it, but the best solution is to switch to a ball or short-grained extruded powder.
