if you haven't seen how the Lee Loader works yet...

It's a neat tool - not at all fast, but definitely neat. And you can't beat the price, really. And... if you're not loading "max" loads, you can rest assured that the powder scoops will be repeatable enough to be safe. If you have the scratch, you can get a powder scale - it's a good investment, IMO - but you don't ABSOLUTELY have to if you just stay WELL into the 'safety margin'.
