Lately I have been weening myself off the RCBS Chargemaster and needed a way to quickly set my Hornady LnL Measure to different throw weights. I was about to order the micrometer assembly but thought of this and saved myself 30 bucks and thought I would share it. Just take your calipers and measure from the top of the adjusting screw to the locknut using the depth blade and write it down. It can be done with the assembly on or off the throw. At .750 it will throw between 40 to 41 grains of Varget which is close enough to require only fine tuning for one of my loads. I would imagine that this could be applied to other throws that use a screw adjusted metering setup. I keep "pet" loads on a piece of tape on the throw. That way I can switch from 24 grains of TAC to 43 grains of 4350 with minimal adjustments
