RCBS uniflow has two drums, does it come with two adjustment screws?

[bballwizard05]

Silly question here, but all my previous loading has been on Lee or Dillon equipment. I purchased a used RCBS uniflow II from the LGS, and I had to dig around to find the other drum (have both large and small), but only could find one adjustment screw setup (which was in the small drum when I bought it).

I assume there is supposed to be a separate adjustment screw (like Lee has for pistol vs rifle), but instead of searching for something that may not exist, figured I'd ask here instead.

What say you?

Yes it does, they fit the bore of each cylinder which are different sizes.
If you are planning a lot of use with different loadings/powders, I highly recommend the micrometer adjustment for it. There is also a different one for each drum.
You can log where your loads are at on the adjustment scale and get very close to your previous setting super easy.
The variables from the previous setting seem to be ambient temperature and humidity, which I found can cause a couple tenths variance one way or the other.
I drop several times to verify weight, then weigh every tenth charge until it shows it's consistent, then weigh every fifty, one tray of cases.
It consistently stays within a tenth with Titegroup and CFE Pistol.
A smooth and consistent lever stroke helps a lot, no pun intended...

'ol shooter knows how a Uniflow works. And, I've been using mine for close to 35+ years. They work.

I put the micrometer on mine. Have a notebook filled with different powder drop settings for 20+ powders. Can go back to any of the settings and get pre registered weights.

Believe it or not, I did a lot of testing for accurate powder drops for my Rifle loading. The large drum was more accurate dropping charges using Varget, 8208XBR. AR Comp and most powders for the 223 Rem. in the 25 or so grain weight.

The small drum wasn't as accurate. It also helps a lot to use a powder baffle and keeping the powder lever at a certain level. You can maintain this by using a large funnel inserted into the powder hopper with the funnel partially filled with powder. When the powder gets to the spud on the funnel, it re fills the hopper at the same level, keeping charges uniform.

Yes, I have a lot of time on my hands.

Thanks for the input. I assumed I was missing a part. I may just get the micrometer, even though I really will only be using this for one caliber at this time. Maybe in the future... more.

All of My Uniflow Powder measures are micro adjust; I use a depth micrometer to measure the protruding adjuster. I have a Pro 2000 with the micro adjust and I have 3 Uniflows, 2 came with Piggy Back 11 attachments and the third came with a stand.

My favorite powder measure is the Little Dandy with the fixed drums. In the beginning it was a big investment.
