i am building a rifle to shoot F-class. I just want to be competitive. In an effort to get more accurate with my powder charges I'm thinking about switching things up a bit. i currently have a RCBS 10-10 and a RCBS 1500 charge master setup. i'm thinking about changing to a scott parker tuned lyman M5 beam scale with an omega auto powder trickler and possibly getting a gem pro 250 down the road. i can't spend the $$$$ that some spend, so i'm looking for the best bang for my buck. i've heard nothing but good things about scott's work tuning scales and i really like what i've seen in videos of the omega auto trickler. anybody have any experience with these items or have any suggestions?
