I really have enjoyed mine it sure speeds up the process. The pros are that its more accurate and faster and will meter those large grain powders such as IMR4350 and 4064 just as well as the ball powders. The only con that I have noticed is that it will drift a little on the weight. For example if it throws a 40 grain charge as it sits there on the scale it can drift and say 40.2 then 40.1 then it will may go the other way to 39.9 even though the charge is correct at 40gr.I checked mine against my RCBS 1010 scale and it was too close to see any difference. I have always weighed every charge because I never load huge volumes of ammo at once.
