I am finding that unique measures erratic after sitting in the Lee pro auto disk for a few hours, the measure will increase by .4 - .5 grains, will measure consistently 8.7 - 8.8 grains then after a few hours sitting will increase to 9.0 - 9.2 grains. Thinking maybe the flake powder settles/compresses thus allows more powder thru the measure? To fix I turn the off the auto disk, remove excess powder, turn it back on and seems to work fine?

I'm relatively new to reloading, about four years under my belt, and gave up on Unique after trying one pound. It meters poorly, burns dirty, gives large ES and SDs, and was position sensitive in my testing. I didn't find any redeeming qualities.

I like Trail Boss for regular .38 special, Power Pistol for .38 +P and .40 S&W, and 2400 for .357 magnum. I also tried Unique in my 12 gauge and was unimpressed as well. I use Red Dot or Clays there.

It may be a jack of all trades powder, but in my experience, it is truly master of none. I strive for excellence in my loads, so Unique was not replaced when it ran out.
 
I just reloaded some 38 special and now 45 LC, I am a hyper person and cannot sit down for long so I reload a few, work in the yard come back reload a few more, etc. I find myself checking every other round for proper powder measure and if its way off I go thru the process of resetting the auto disk!

Waywatcher, I appreciate the input, thanks!:)
 
Your experience is not unusual. Depending on the equipment used Unique will do fine or as was said by someone here: "It meters like rocks".
 
I don't think people with a DILLON run into that problem. Every time you pull the handle you jar the powder to compact it. I have several & long as you wipe them down every 400-500 rounds no problems. Like that wabbet beating on the drum.---PS--UNIQUE IS ONE OF THE BEST ALL AROUND PISTOL POWDERS OUT THERE.

Powder will settle.
A trick I learned long ago is, after filling the reservoir, to tap it 20 times on the left and again on the right to settle the powder. I use a long thin blade screwdriver and tap with the plastic handle.
About the same time, also gave up on Lee powder dispensing equipment. Not their finest act.
Have also found that, when running at the right pressure level, Unique is one of the better performing powders in medium revolver loads, regardless of the SD numbers.
 
Try this, I'm going to.
How to make a powder measure baffle - AR15.COM

I finally decided to make a baffle for my Lee Perfect Powder Measure –– got one done and it really does even out my throws of Varget, especially. I intended to make one like AeroE's but pop cans require a 10 cent deposit here in MI (and yes, I'm that cheap). I found something perfect and free (not exactly, but you get the idea). I used the cap from a prescription bottle –– about 2-1/8" across. I removed the soft plastic liner from inside, then cut out 4 sections of the short ridge in the inside of the lid (maybe unnecessary), then drilled 4 holes (3/8" each). Then I cleaned up the holes a bit with a round needle file and a knife. I put the lid in the measure (upside down), and filled it with powder. If you have that measure, you know that it's funnel-shaped at the bottom. This baffle rests perfectly at the top of that funnel and powder flows evenly down through the holes to the bottom of the measure. I'd guess about 250-400 or so grains of powder rest below the level of this baffle, so there's a light but consistent amount of downward pressure on the powder below it. Sure, a baffle shaped like the one above would look nicer, but this was fast, free, and easy (and it seems to work ok too). Thanks for the inspiration, AeroE!

Following the KISS principle I use Unique for just about everything from 38 to 12 ga, except Trailboss for 45 LC. I have found that my Spolar shotshell reloader throws very consistent charges of Unique because it has that vibrating motor that vibrates the primer feed and the powder. My Dillon 650 stays dead on throughout a loading session in part I think like 4barrel said because everything gets a good jar whenever you pull the handle plus the automatic case feeder vibrates the whole machine. When I had Mec shotshell reloaders I had a problem with consistency due to static until I added a metal baffle between the powder bottle and the charge bar. Also have seen really good results with taping an aquarium pump to the frame of the loader to keep everything moving consistently with the vibration. I found that my RCBS uniflow measure throws consistent charges of Unique when I let the metal handle whack the frame while operating it but you really have to watch the powder adjustment die on that one because it will vibrate loose if you don't tighten it enough. I don't know anything about your Lee powder measure but suggest you contact the manufacturer because I don't think you should be having that much fluctuation
 
I was never too keen on Unique till I started reloading 44mag, lead target loads specifically. I always had a cpl pounds in my inventory, but found other powders were better for the various calibers I was loading. 38spl=W231, 357mag=many options, 45acp=bullseye,titegroup, 9mm=titegroup. I'm currently experimenting with W231/HP38 for my lead target loads in 44mag as my supply of Unique is almost exhausted.
 
I use Unique with Dillon powder measure with no problems. I load .38 special, 9mm and .41 Mag moderate loads. I may switch to Power Pistol for the 9mm though.
 
Unique - my first powder, and maybe the last one I'd give up.

But it is a royal PITA in the Chargemaster 1500 - I get more overthrows with it than with anything else. Bridges like crazy. I don't find it to be as bad in the Uniflow, but - yeah - that's an issue.
 
Unique

When I started reloading in 75 I settled on Bullseye,Unique and 2400 for my three " go to" powders.....over the years I have loaded and shot about everything that has been on the market.....but I still load my 4" bl 41's,44's & 45 LC's with Unique.....used to buy it by the keg and have shot thousands of cast bullets downrange with it.....use an old Lyman measure to meter it. I can load heavy in the shorter barrels and not have a huge muzzle flash.

Ive heard a lot about it proforming poorly in Measures, but this is realy the first time in a post ive read about diferent measures reacting diferently. Im guessing you use a Lyman 55 right? How does it work in it? Im working on HP38, and 2400 loads now, but thinking of picking up some unique becouse its a mid range choice, and will also work in all the rounds I load. It will be nice to have a lb or two hanging around for the next time we get the panic buys like now.
 
Powder measures

You are correct, I use a Lyman 55 and also a Herter's powder measure that I have had since the early 70's.....I think it is probably made by Lyman for Herter's....but I have used both of these for decades and have metered a lot of powder thru them. Unique is a very flexible powder and it has served me well in the short barrel magnums, the 44 spl. and 45LC.....Anymore when I buy powder and primers I always buy twice what I need....just for those "panic occasions".

My C-H powder measure does a pretty good job of metering Unique, but I like to weigh often. My previous powder measure, a Lee PPM, did only a fair job with Unique so I mostly used a dipper and trickled a weighed charge. I like Unique and I'm not concerned with the "reports" of "dirty burning" because I don't wear dress clothes when I shoot (my white tux is worn only for dinner out!) and I can always wash my hands after I shoot a bunch. I have only shot about 300-350 rounds of Unique loaded 45 ACP at one time in my 1911 and never had the slightest problem with the gun malfunctioning because of "dirty" powder. I clean all my firearms after each session and I choose powders by their preformance not if I get my hands sooty. Some things are just overblown and meaningless...

Unique meters fine through my Lyman 55.

For those who say it is dirty, try using it in hotter loads. Unique likes to burn in the medium to high pressure range. When used in these applications it is anything but dirty. If your choice is between Unique and Trailboss, that is the wrong application for the former.
