+1 on what Kmrere says. The Lee dippers will get you started, and if you follow their loading tables you certainly won't get in trouble, problem is they are far from accurate as far as what Lee says they will hold. You can be pretty consistent with their dippers, , but as far as their holding what the tables say, forget it. My recommendation, get the Lee tool, and make some ammo. Then with all the $s you are going to save, get just a simple balance beam scale. You don't need a high dollar electric scale, the balance beams have made good ammo for a long long time. Then make yourself a few dippers that hold what you want them to, not what Lee lawyers limit them to. Make some more bullets, and someday if you're still wanting to upgrade, a measure will be the next step.
