For years I used a dipper and scale. About three years ago I bought a RBCS Uniflow at a gun show for $50. Didn't know at the time it had a large cyliner installed, meant for heavy rifle charges. I called RBCS to ask them about it. They said you have the wrong cylinder for oading pistol bullets. I ask how much to buy the small cylinder and they told me no charge, give us your address. (This is a $25 part). I installed the small cylinder and now load Unique, 2400, and Bullseye for 9 mm, .357, and .44 mag. It will consistantly measure within 0.1 grains and so far hasn't leaked. Needles to say with RCBS customer service like this all of my reloading equipment is green.
