I just got my RCBS 1500 combo. I set it up, went through the calibration, thought I would through some big stick powder to give it a try.....
AWESOME! I am amazed at this tool. I was suprised at how fast it is. I was using 4064. I also use 4831sc and Varget, I bet those powders will run through it faster but I wish I would have bought one of these a long time ago. I also have a Rangemaster 750 that drifted up and down about 3-4 grains and was hesitant to get the combo but there is a huge difference between the 2. Just thought I would share my thoughts.
Thanks.
