[ARCHIVED THREAD] - Yeah or nay: Baffle in Dillon Powder Measure?

Posted: 2/20/2018 12:43:55 PM EDT

I installed a baffle in my Dillon Powder Measure a few years back and can't decide if it helps or hinders.

I have the PM apart to clean and may or may not put the baffle back in.

What's everyones thoughts?

Thanks,
John

all mine came that way so I would say yes.

There is a baffle built into mine, so i would say yes.

I'm also not sure how they could be a hindrance.

The baffle is to keep the weight of the powder over the slide consistent. That makes it throw more uniform. But your decision.

How much it helps depends on the powder.

I assume you're talking about something like in the pictures above. I use them and have had very good results with them using Power Pistol and 2400. It's hard to say if they're noticeably better than the normal single baffle that comes built into the hopper.

I should have mentioned to start that my PM is 20 years or more old.

I thought I added the single baffle a few years back but am not certain.

Thanks for the replies!

No baffle in mine and its about 13 years old. Should it have one?

Dillon PM's come with a baffle installed.

So no added baffle needed.

With proper technique, a Dillon PM as it comes from Dillon will throw ball powder exact, flake + or- .1 gr.

You can see the baffle in the pic above, just above the screw. It's a clear plastic part.

I've never had a problem with the integral baffle in the dillon. No reason to add one. Might want to read this...

Dryflash3- thanks for getting me on the right track: I was addressing the drop in aluminum baffle and not the integral plastic baffle.

Twitchinator- thanks for the link. I just buffed up the interior and powder bar channel on my PM and am on the fence about re-installing the

aluminum baffle.

the Dillon baffle is molded into the clear plastic.

If you want to know why a baffle, the problem is vibration.
On a progressive the charge bar is sitting in the fill position, vibration from walking past or working on your bench will be making the powder settle,
making the charge heavier.
On a progressive this can be a problem.

Baffle or no, I recycle the first few charges when starting a new reloading session.

I used my Uniflow for 25 years without a baffle. For $2 I figured why not. So now 6 years later I still don't know if it's doing anything positive but I'm pretty sure that it's not hurting.

I never leave powder sitting in the Dillon, unless I'm actively loading.

No baffle in mine, but when I'm done reloading I put the powder away.

Some posters are missing the fact that the Dillon PM comes with a built in baffle.

I tested mine by measuring each drop as the level of powder fell under the baffle. I was surprised how accurate it remained until there was very little left in the stock powder measure with no aftermarket baffle.

This. An extra one isn't needed.

Nay for me.

I made a baffle for my Lee dispenser out of a cat food can lid. Works great.

I'm curious if anyone has used one of these extra baffles while using IMR4064 , varget or the like and did it make any noticeable difference?
