Buy a Targetmaster and a set of tuned beam scales from Allan aka 1066.
It works, it's VERY accurate, it's quick if you use something like a Lee Dipper to give a 'nearly' charge - the next charge will be waiting when you've seated the bullet in the previous case, it's made in England, it works out cheaper than the electronic combinations.
Do a search on here for info. or Google it...
