RCBS Uniflow

IHMSA Shooter · January 9, 2009, 11:55 AM

I have an older one (10-15 years old). Have used mostly for rifle loads and some magnum pistol.

Does anyone have experience with the Uniflow and small charges of pistol powder? Specifically 3 grains of Bullseye.

Is it worth it to fool with Uniflow for that charge weight or should I just stick with a Lee dipper?

I used to load 38 Specials with a Uniflow, IIRC 2.8gr of bullseye. It works well.

Thanks Scorch. I'll give it a whirl.

There were two different drums available for the uniflow, a large one for large capacity rifle loads, and a small one for medium rifle and pistol loads. As I remember, the uniflow came with the small one (someone help me here to make sure). I use the small one for 3.0 of Bullseye with no problem.

My Uniflow is probably 30 years old and it came with both the small and large cylinder.

I use only the small cylinder, and it works fine for small charges of just about any powder. I do use a baffle inside the powder hopper.

I have never used the large cylinder since I weigh all my rifle charges.

Use the small drum and a powder baffle and it works just fine.

A micrometer head makes changing settings easier.

Since you have to remove the micrometer to change the drum thus loosing the zero, I have two Uniflows.
One for each drum size each with a micrometer head.
You can return months later to the same setting and drop the same load.

The QC upgrade kit may also work with it, in which case you can switch between small and large metering inserts with no tools. Unfortunately, they do not have micrometer adjustable QC inserts.

My Uniflow came with both cylinders, and I've loaded thousands of rounds with 3 grains of Bullseye. I trust it more than I do the charge bar on the Dillon, and I've loaded tens of thousands of rounds with that also using 3.0 of BE or less.
