I hate this powder measure with every bone in my body.

[Stopsign32v]

I've never enjoyed using it. It's difficult to acknowledge that I have been using it for the past 13 years. It has always had the same issues to me...Too close to the work bench, leaks like the Titanic, and gets so crunchy.

I have taken it apart and cleaned it, degreased it, even polished it. Same old crap...Does half decent and then gets so bound up that it's almost impossible to use. I have always told myself enough is enough but I never would get another powder measure. Money could always be spent somewhere else.

Yesterday was the day. I was reloading CFE Pistol powder and it started getting hard to use. I powered through it and then I realized I wanted to throw together some 357 Magnum loads. So I cleaned it out and put some 296 in there. It became so hard to use that I was moving the stand just getting the handle to move. I decided money wasn't a factor and that this morning I would solve my issue.

It is difficult to put into words what I have been missing out on. I'm just shaking my head here. The Uniflow 3 is just simply a joy to use. That is the best way to describe it, a joy.

I have and enjoy a Uniflow 3. I have noticed that it is not very consistent with small charges of pistol powder, say 3.5 grains or under of something like Titegroup or W231. I think the one size fits all drum might not be the best for those small charges.

It is my understanding that these are the absolute best. https://www.harrellsprecision.com/co...powder-measure

I have two Uniflow measures, one with the small chamber and one with the large.

I also have the Lee Perfect (same as the OP's) and yes it leaks spherical powders but I really like it for extruded ones (stick type).

At more than double to more than triple the price I'd hope that Harrel's was the bee's knees.

I do not like mine either and have not used it in many years.

Interested in if there is a solution but the ChargeMaster has solved the issue for me. There are reports there can be drift with the CM but I have never had the problem.

Yeah, I have a lot of the equipment. I had that perfect powder measure for about a week and said. Nope picked up a couple un flows and I’ve never looked back. Now in fairness, I am quite happy with their auto disk and their auto drum and I actually have a pre-auto disk safety disc. That’s a bench mounted powder measure. Just not the perfect powder measure don’t like it never did.

Neil Jones and Harrell's is about as good as Culver type powder measures get.

Get the powder baffle and you'll like it even more. Canted two sides metal plate that distributes the powder inside the cylinder that helps prevents bridging

Back when I first got serious about reloading I had a Lyman. Loved the thing and could get into a good rythem with the handle then knocker repeat.
Got out of reloading and sold all my stuff.
Got back into it about ten years ago and bought the Lee, have had good luck with Lee products but the powder measure lasted about 20 rounds and it had to go. RCBS Uni now

The RCBS Uniflo with the small drum (!/2 inch hole) and a micrometer adjustable setup will make a believer out of almost anyone.

[Shawlerbrook]

I like my Reddings but the Lyman 55 still has a place on my bench.

[Winger Ed.]

I'm a repeat buyer for the Hornady, the new style with the baffle is the real deal.

However; the rotary drum concept will always have issues with large grain or stick powders
as it tries to chop the individual sticks as it rotates.

[Polymath]

I ONLY use cylindrical stick powder in my Lee thrower. (Top post)

I agree with that completely and noticed that as well.

[beemer]

Just playing around, I lapped the cones and it actually helped but not really worth the trouble. The only thing I like about the Lee is the hopper cut off.

I have two old Herter's powder measures, pistol and rifle. The holes in the drum are 1/4" for the pistol and 3/8" for the rifle. The pistol measure will do small weights of something like 231 but is too small for flake powders like Unique. They are good measures but do not have a micrometer adjustments.

Can I add those to this setup?

I was really disappointed to see that this didn't come with the baffle. I thought it would...

Look at the differences in your 2 set ups.
Lee a sheet metals stand with little structural bracing. This stand cant be taller as then it will be more spring than stand. the measure is plastic inviting static and stickiness, small funnel area into the measuring drum. there is also a cut off that restricts flow. Loose tolerances encourage leaks and binding.

The RCBS stand is solid metal with stiffing rails to aid support and measure operation. This is rigid and can be taller. The body is cast iron and machined to fine finish drum is steel and again finished accurately and with fine finish, this promotes smooth operation and little leakage. Also look to width of measure it is wider giving more bearing area and more area to seal. Funnel into drum is much larger.

A dimple effective baffle can be made with scissors and an old pop bottle. cut a section from the bottles center and split down one side. fold this in half You may need to warm it to get it flat. You want to cut it oval about 1/2" longer than width. On an oval that fits the drum when opened up. Cut 2 1/4" radiuses ( 1/2" dia) bottom dead center of the legs. Warm and open up so there is some grip then slide in drum legs should catch on lip between drum and body. This will allow 2 1/2" streams of powder into drum 180* apart, and allow measure to work from a set amount regardless of whats in the tube. This smooths out operation evening out the weight of the powder in the cannister to whats flowed thru.

As a experiment fill measure 3/4 full of a given charge set to a given charge and weigh charges to almost empty. with out the baffle as the powder level drops so will the charges with the baffle they stay even much longer.

Another way to accomplish this is to set a larger funnel in the top and work from it
