I am surprised no one answered you on this. You can go a few of ways:
1. Stick with your system - however, I don't use a powder throw for rifle.
2. Use dippers and a scale. you can trinkle the fine adjustment either by dipper or trickler.
3. RCBS ChargeMaster combo - I LOVE this system. you can run a charge, charge a case and seat your bullet and your next charge is ready for the next round. Very precise for rifle. I will say that I don't use the ChargeMaster Combo for pistol because it is too slow. For Pistols that I still load single stage(I have a couple of XL650's that are set up for 9mm and 45acp.), I use my old faithful RCBS Uniflow.
Cheers, Mate.
