What a Difference a Baffle Makes!

The other night I was loading up a batch of .45ACP rounds with Bullseye powder using my RCBS Uniflow powder measure. I was weighing out the loads trying to nail down my desired 5.5 grains. I finally got it, then weighed about 6 more and got everything from 5.3 to 5.7. This wasn't the first time I've been frustrated with wild charge discrepancies, but it was the last.

I went online searching for what I could do. I was afraid I might have to buy a different powder measure. I discovered the powder baffle (which I'd never heard of!:cuss:).

I dropped by my local shop, picked one up for $8.99, installed it in my Uniflow, and what do you know - I threw 5.5 grains about 10 times in a row!

So I just wanted to let any other novice reloaders out there who are frustrated with variations in their charge weights know - a powder baffle is a great improvement! (This must sound like the ABC's of reloading to you experts). I suppose you could pretty easily make one yourself, also.

i too was amazed at how much the baffle in my LNL Measure helped with all powders and consistent throws.

Powder hopper baffles are the best thing since pockets on a shirt!
There's a little set of easy to make patterns you can download.
Problem is, I don't remember just what it's called. Some one might pop in with how to find it.

Has anyone here used a baffle on the Dillon powder dispensers?

I agree, they make a huge difference. Just other day I was using W-231 and couldn't get consistent charges with variation of +- .2 gr. Put the powder baffle in and the variation went away. I don't understand how they work so well.

I've never used a powder measure without one. But I've only been at it about 14 months.

Yes, I find the baffle indispensable in a powder measure. All five of my drum style measures have one. But technique is also important. Variable technique results in variable powder charges.

There are folks that feel the baffle has no effect.

Good technique and a baffle go a long way with throwing consistent charges of Unique. I made mine from the on-line pattern out of furnace duct sheet metal.

I have an RCBS tube type and I made mine out of a 2 liter bottle cap; just cut three equally spaced triangles out of the side of the cap

This gets you to the PDF pattern sheet to make your own.

Argh! that ain't it.
It's Uncle Nicks "something". I'll find it someplace.

Uniquetek sells a baffle for the Dillon.

My Dillon powder measures have the baffle built in already. I can set mine to 4.0gr and throw 10 charges. I can weigh those 10 charges, and they will weigh out at 39.8 to 40.0gr.
