Uniflow baffle not fitting?

I bought a used rcbs powder measure, which I can only assume is the uniflow after looking at pictures.

So I got a baffle for it, wanting to help even out loads, and I can't get the danged thing to stay "upright"

After a while of fanageling I got it in this way



But it's very unstable, and wobbles and tips very easy. Is this a uniflow?

Yes, that is a Uniflow and yes, the baffle as installed is correct. With the powder measure vertical the bend in the center of the baffle points upwards. There should be two locking bolts on the holder, one above and one below the holder. It should be stable.

Also, as a side note you may want to reduce the image size. Saying it is large would be an understatement.

From the pic can't quite see the measure to verify measure type, or how the baffle fits.

My Uniflow is 2-1/4 in. in diameter. The bottom of the RCBS baffle rests right at the seam where the green plastic meets the metal cone. The bend faces up as stated. After installed, it did make a notable difference in consistency of powder charges.

Is that 2-1/4 at the top opening, or where the plastic meets the metal

Your powder measure is an RCBS measure but it is not a Uniflow. It is a Quick Change model. The Uniflow plastic hopper isn't tapered at the bottom. RCBS sells different baffles for the different models.

The cats out of the bag, but the 2-1/4 diameter is the plastic cylinder. Top of the metal cone where it meets plastic would be same, then tapering down from there. Where plastic meets metal is where baffle sits.

RCBS has great customer service, they should work with you on getting the right baffle. Currently you have a mismatch.

As mentioned, that's a Uniflow, but not the standard version.
The standard baffle is for a straight-cylinder hopper.


You need to either change hoppers, or change baffles.

Well I'll be. Had my first run in with rcds customer service, and wow. Just wow! Superb! *wish Lee was like that... But they're go broke with all their garbage* took less than 5 minutes. Just told the guy I accidentally bought the wrong baffle and "OK, what's your address" !!serious! Well, I bet you all know how stand up rcbs customer service is, and I've heard only good. Was good to get it fixed, even if it was my fault

At risk of stating the obvious, they didn't get where they are by being difficult to work with

I would like to check out the do it yourself baffle by Unclenick, but for some reason by Adobe software keeps self corrupting even after I repair it, big PITA!

Below is another copy made into PDF on other software. Probably won't make a difference. You may want to download and reinstall Acrobat Reader.

I made a baffle for my Uniflo from Uncle Nick's pattern last year. Thanks Uncle Nick.

Thanks Unclenick, I have tried repair and also uninstall and reinstall Adobe Reader, the right version for my operating system, and nothing works. So I found and loaded a software called "Soda PDF" that allows me to read all PDF files. I guess something in the system must be stopping Adobe Reader, but if Soda works, I'll just stay with that for now.

May want to run a registry repair program. You can get JV16 Power Tools with a couple of weeks full functionality before you have to buy.
