Ok guys,  I've been reloading since 1980, same time I started casting boolits and shooting a muzzleloader.  But I've never reloaded a black powder cartridge.
My favorite measurer is my old RCBS Uniflow, checking things with my Ohaus scales.
I understand it's not a great idea to use the RCBS with holy black. 
So... what's my options and choices? 
I have a feeling I'm be looking for an old B&M, but I thought I'd ask. 
So mote it be
Yip

I’ve used a Belding & Mull for years, price dependent today would probably buy a new MVA. Nice B&M could cost nearly  as much as the MVA

MVA for sure.

The B&M measure works well if you have a drop tube big enough for your power charge.  The Lyman 55 also works well. I have one I put a larger brass hopper on and that makes it quite nice. 
I picked up a used one from this site I think and I used it to play around to see if I could come up with a solid set up to bore out the measure to fit a brass hopper and I did. it worked quite well. 
I have been told that the Readding measure works very well also. What ever measure you choose, you will have to take it apart and clean it regularly. 
Any measure that can be adjusted to throw a large charge and hold constant measurements would work.

I have two B&M powder drops both with the measuring tube. One has the brass hopper and one has the plastic hopper.
$125.00 shipped for both together.
