Have been using a Chargemaster for years (reprogrammed and straw trick with small notches in straw) and yet I've been getting a ton of clumpy overthrows with H4350 last few months. On the order of 30-50% of charges thrown. It was getting beyond annoying.
However, I just found a post on another site were member said he had much better luck when raising the front edge of the scale by 1/4" or so. It helps to uniform the powder and keep it more "level" in the tube as opposed to clumping towards the exit of the dispenser when speeds kick down.
I just tried this and I have loaded 39 rounds with 2 overthrows. This is night and day different! Wanted to post just in case anyone else uses similar setup. The check weights still hit 49.99/50 grams and powder tray is exactly the same weight as before. Scale calibrates normally so it still is within the precision level of +-.1 grain. Hope This helps those in a similar situation!
