I like the Uniflow.

I upgraded mine with the Quick Change Metering Cylinder. I have 6 or 7 QC metering screw assemblies adjusted for loads from 10 gr. to 100 gr. So, if I'm gonna load a 60 gr. load, I install the metering screw assembly that's set for a load in that vicinity.

They make small and large assemblies. The small one has a sleeve that cuts down the diameter to that of the Uniflow Small cylinder. Those can be set for light loads and are accurate.

I don't have to do a lot of adjusting, just fine tune the appropriate assembly. I made a wood block with holes to hold the assemblies, each hole with a label.

Works for me.
