You do not need any precision type dispenser. Any dispenser that can dispense the amount of powder you need to within one or two grains, is perfectly fine.

In my opinion, the old orange Lyman 55 with the cast iron body is great to have. Even if they look old and beaten up, they generally work perfectly, and can dispense up to 120 grains.

I have salvaged a few old powder measures over the years.

If the Lee Perfect powder measure can dispense the quantity of powder you need, use it.
