Have used a Hornady bushing powder measure for almost all loads up
to about 9gr for 30 years now. My question is about drum type
measures like the RCBS Uniniflow or similar. With the bushings I'm
limited to specific charge weights. Say my gun likes 3.3 gr but the
bushings I have only make 3.0 and the next larger 3.6. With the RCBS
I could get exactly 3.3 but is such a small charge repeatable or would I
have to weigh each? The bushing measure is just so much faster. With
real light loads you can get into pressure problems quickly. Just how
light a charge you'd feel comfortable with in a drum measure? What
equipment and procedures do you use for light charges?

Why not drill out 3gr bushing to 3.3gr. You could also fill larger one, with epoxy or hot glue and drill correct sized hole. Emory paper wrapped dowel should smooth it up, if needed.

I agree with Robert.
Assume you have the chart:
https://www.hornady.com/assets/files/powder-charge-
bushings.pdf

Bushings cost about $5, so getting a smaller one and
opening it up is just some emery paper on a dowel rod
and use an electric drill (aka poor man's lathe).

Once upon a time 55 years ago, I had one of the first
Pacific shotgun loaders..no bushings, just complete
bars, $10 each. I just modified (drilled one bar
out)to take other company bushings. Worked good for
35+ years.

Robert's, fill and drill is probably the simplest.

Also, measures are cheap on e-bay and last forever.   
If you will want more various loads, get a used Lyman
55.

Fill/drill is a good idea.

The charts are a guide but they are usually two sizes off from reality. I
wish it was as simple as looking at the chart. I do have good records
and logs from my previous loadings that are accurate.

I'm still wondering how light you feel comfortable with a drum measure?

Fella's;

I'm not going to get into this one. My sorta-two measures
are the RCBS Uniflow and whatever the charge bar on the
Dillon is for that caliber. The Dillon is always set below
max & well above min. With the Uniflow I'll measure about
every 5th or 10th case full depending on my history with
the load & powder. I do have both cylinders for the
Uniflow.

Straight cylinder measures are very good.

for small charges small diameter cylinder (holes) are
not as accurate; so a larger shallow hole is
preferred.

I think I'd make one out of 1/2" dia aluminum rod,
calculating the volume compared to the 3gr you have.
Make it smaller than calculated, easy to make open up.

If Hornady is comfortable at 3 grs, I'd not worry if I
made a 2.5 gr.. As you know as the charge goes down
the bore gets smaller, and powder can jam.

I visual check each round before seating a bullet.
If is looks low or high, I kick it out and load again.
