Does it meter well for you?

What kind of powder measure are you using?

This is my first go-round with Unique & it's metering like crap! :(
It's varying .3 -.4 grains.

My usual go-to powder is Tite Group & it measures PERFECTLY in my Dillon powder measure.

Most throws are +/- .1, but a + .2 or - .2 is not uncommon. I can't see it on target at 50 yards and under. Maybe from a vise I could. Redding 10X.

If Unique was terrible, it wouldn't be one of the most sold powders we have to load with. ;)

Don't sweat it. :)

I have no problem with it.

I have three Lyman-Ideal #55 powder measures.

You might need an aquarium air pump taped to your measure hopper to vibrate it.
Or maybe a powder hopper baffle might help.

I'm using a RCBS Uniflow. I experienced a similar variation in throws until I had run about a pound through it, it was brand new.

Not sure if it matters, but I also use the small micrometer cylinder and a baffle in mine.

I get about +/-.1 gr variation. Having the hopper 3/4 full or more helps me stay consistent also.

I use a RCBS powder measure. It takes me a while to get Unique settled in and throwing consistant. Once it's settled in it will throw, for me, a little over +-0.1, call it +-0.15. I don't shoot good enough to notice the variance. Maybe if I was a better shot I'd see the varaince.

I get consistent drops with a Lee PPM if I remember the following:

>Keep the hopper half full or more
>Use a consistent lever force
>When starting, ditch the first five and then go on a run with it
>If I stop dispensing for more than a minute, start over and ditch the first five again

On a bad day the drops will stay within +/- .2 and that works well with what I'm loading.

I get similar spread in my pistol charges. I have no problem with .3-.4 spread (+0.2 grains, extreme). My guns and targets don't know the difference, so this doesn't bother me in the least.

If you look at Alliant's data and google common charge weights as reported by users, you'll find in many cases that there's a huge range of charge weights that are commonly used. They all work. A difference of a few tenths isn't usually going to matter so long as you're starting with good data.

The important thing is that the variation isn't due to bridging. Unique flows great through my PPM. The measure is throwing the right volume. It's just the powder isn't very fine/regular. So I'd say it meters ok, it's just not very uniform in density. There's some variation, but it's a limited amount. You're not going to run into any serious trouble, unless you're shooting for 200 meter groups.

I gave up trying to use it in my Lee auto disk with 380 loads. Plus or minus 0.2 gr variation is just not acceptable when the difference between starting and max loads is only 0.5 gr.

My Hornady LNL AP typically throws Unique in .1gr increments either side, occasionally there will be a .2 or .3gr difference. I'm usually not close enough to a max load and/or I'm not participating in a competition so I really don't care too much. However, were I close to a max load I'd probably check a lot more casings.

It meters close with my Lee Pro powder measures however I also weigh each charge even for target loads. I have a few though that meter better and some worse. For those that don't I use the dipper method.

I've reloaded about 25 rounds so far, & still not getting what I would call consistent drops.
Target is 6.5 gr - I'm seeing 6.3 - 6.8 - weighing every charge on 2 scales to make sure.
A Lyman/Ohaus & a Pact BBKII.
My PM drops perfectly with finer powders like AA5 & Tite Group.
It also works perfectly with stick powders like Varget.

Makes for extremely slow reloading when I have to weigh EVERY charge.

When using Unique and my powder measures for single stage press loading (batch charging trays of cartridges), I get plus/minus 0.1 grain.

Not so good on the Hornady L-N-L progressive, but the charge weight creeps up. It is getting better as I learn what the set up of the powder measure on the progressive.

I get plus/minus 0.1 grain with 700-X on my Dillon SDBs. Have not run Unique through them yet.

I used an RCBS Little Dandy for a long time then switched to a Redding 10-X for single stage press loading of handgun cartridges.

I have switched the Hornady progressive over to a Redding 10-X and the variance is getting better.

For me and batch charging, I find the variances are less if I minimize the vibration of the powder measure. Of course, that is not an option on the progressive as it cycles through its process.

And, I use an electronic scale to weigh my charges.

Works great for me - I use a single stage press and have one of those auto dispensing scales :rolleyes:. I imagine it might be a pain in something that will work with a progressive loading setup though.

Even with some variance like you are experiancing. Unique has always provided very accurate, consistant shooting loads.Just go with it and have fun. Try power pistol or AA5 next time, they meter better but accuracy is the same.

Its the only powder I use for pistols. My RCBS uniflow throws it and every powder +/- .1 which is close enough for me as I hardly ever get to max loads with anything.

Unique is the powder I began stocking up on over a year ago, so I am committed to it for the next few years.

Hondo 60

Using an electronic scale by any chance?

Yes & No - I've been weighing each charge on a Lyman/Ohaus scale.
(and checking it on an electronic scale - both scales are in agreement.)

Sounds like I need to wipe the PM down with a dryer sheet.

I've been using Unique, well, forever. It was the first powder I bought when I started handloading in the early 80's. (Nineteen 80's guys, I'm not THAT old.) I continue to use it because it works so well. In my Redding measure, I get +/- 0.1 gr consistency. It's important, though, to use a good technique and rap the handle at the bottom and top of the stroke. Use a consistent stroke and rap it the same way each time. Don't let the hopper get below 1/2 to 1/3 full. Also make sure the powder has settled in the hopper before you "throw for score." Unlike spherical powders, flake powders seem to take a while to settle in the hopper - up to 15 throws in my experience.

January 4, 2013, 09:04 AM
In my LNL powder measure, the only thing i've found that meters better is H-110 and 2400, which are pretty much spot on. Unique is usually +/-.1 with a .2 on occasion.

800-X on the other hand.....:banghead:

January 4, 2013, 09:28 AM
I've used unique for a few years now, love it for several pistol loads, hate it for anything smaller than 9mm because on the smaller cartridges I can't get consistency.

Its actually my favorite for .40 S&W and .38 Special loads

JLDickmon
January 4, 2013, 09:37 AM
Being a flake powder, I do find that my Lyman 55 likes to shear a flake in the cylinder every now and then. I generally set the measure up to throw a couple tenths under my desired charge, then I don't sweat vibratory compression as much.

Like the one guy said, if it's had the chance to settle in the hopper, ditch the first few then go ahead and charge. And I keep the hopper fairly full as well.
Same with Blue Dot and Red Dot as I use a lot of those powders too.

Blue68f100
January 4, 2013, 10:31 AM
I quit using Unique for that very reason. A 0.2+gr variation is not acceptable in my book. I can detect the difference when shooting. If your loading at or near the top end you are more than likely going over the published charge. I can get a consistent drop doing the tap dance but you can't do this on a progressive. I only use ball powders on progressives.

Unique meters like Corn Flakes. It works well in a lot of calibers but I don't use it in small volume cases where a 0.2+gr (0.4gr) variation is equal to 10% swing or the workable range.

Hastings
January 4, 2013, 10:59 AM
My RCBS Uniflow works okay with Unique, but I only use the Uniflow for lower power loads or "plinking loads in my 45colt. I hand measure each charge with a mechanical or digital scale if I intent to use the rounds for hunting or target shooting. My velocity deviation goes way down and my groups get much tighter with the individually weighed charges.

I love Unique, but it's not necessarily my favorite powder for any cartridge.

I use a RCBS uniflow on my Hornady projector and it throws spot on just about every time. I use a baffle and fill the hopper and go for it. The only powders I have problems with are stick powders.

I think if you put a baffle in, if you don't already have one, and cycle it more than the 25 times you will likely find that it will do just fine for you.

I use Win 231, WSF for 9mm and WST for 45acp. WSF will have a softer recoil over the 231. But I mainly use WSF for 124gr which is what I shoot 99.9% of the time. These powder flow like water and will give you a dead on charge.

Using an electronic scale by any chance?

Really curious why you ask this question RC....I've noticed some funkyness from my electronic scale....*At times* after I tare whatever I'm putting the powder to measure, it will just suddenly and inconsistently add .5gr on at random times for no reason. I know this isn't "normal" behavior and I watch for this behavior and correct it by performing the tare again.

I wonder what you've seen with electronic scales?

Steve in PA
January 4, 2013, 06:10 PM
I use the RCBS Uniflow and Unique is one of the powders I use. The key is to use a consistent rhythm when using the RCBS.

cfullgraf
January 4, 2013, 06:26 PM
*At times* after I tare whatever I'm putting the powder to measure, it will just suddenly and inconsistently add .5gr on at random times for no reason.

Are you giving the scale time to re-zero itself after pushing the tare button or just pushing the button and dropping the charge on the scale?

My electronic scales take a little time, a number of seconds, to re-zero after pushing the tare button. They both have an indication in the display that shows the scale is not ready to weigh yet. One flashes a little marker in part of the display even if the display show 0.0. It is not ready to weigh until the marker stops flashing.

I use a lot of Unique. It has always metered OK for me in the Lyman 55.

I will say that it is important to develop a consistent procedure that you can repeat. I never vibrate or knock the measure when the handle is in the up position. Just let the powder settle then cut it. Always try to move the handle at the same speed each time. You should be able to get results down to .1 gr variance with some practice. One other thing, the first 10 seem to vary more than those after. Might be something to do with the powder settling in the hopper?

Not particularly.

Lee.


But I use it anyway, when i'm out of other things, or first trying load workup.


I keep 4-5#'s on hand- its very versatile.

Yep, in those scenarios I can measure 15 charges just fine then suddenly they will all start reading .5gr more than what I am actually pulling.

buck460XVR
January 5, 2013, 12:59 PM
Unique is one of those powders that folks that use dippers like, because it shoots very well when measured by volume. A powder thrower measures by volume, not by weight. It's just an automated dipper. We as reloaders using a powder thrower, just adjust this volume by using weight instead of volume/dipper size charts. I have found that weighing individual loads of Unique as opposed to throwing charges of consistent volume makes little or no difference in accuracy. For me, consistent volume is obtained using Unique in a Uniflo by double tapping the handle, using a consistent stroke and keeping the hopper full.

January 5, 2013, 01:17 PM
Hondo 60: I have used Unique for a long time. And I use a Lyman 55 powder drop for about the same lenght of time. Never experinced any problems, I drop straight from the powder drop 60 cases in the tray at a time and then weight several of them just to check. But I have never found a problem. I have loaded a lot of ammo with Unique & a Lyman 55, they work for me.

Hondo,

I can't trust Unique in any of my 3 powder measures. I just loaded 100 327 fed mag today with unique and always measure unique on my digitol scale, after running the measure about 10 cycles or so I started weighing and measuring.

The first 8 or so were exceptable at .2 +or- , then I get a .5 which is .4 over my target max. I wound't use it without measuring every load as I have been doing. I am using an RCBS Uni-flow and set it for 2-3 tenths under my target weight and still end up dumping a lot of them back in the hopper for being over. It does the same in my Hornady and my Lee measures.

I like Unique but won't use it with out weighing every charge, and I'm not paying over $200.00 + for a Redding 10x to get it down to +or_ 1 tenths with variences.

Their are to many other powders out their that meter really well and work as good as Unique.

ScratchnDent
January 5, 2013, 08:26 PM
I use Unique through a Lee PPM for 90% of my handgun loads, and am perfectly happy.
I have run umpteen 20 shot comparison strings versus factory ammo, and the extreme spreads and standard deviations of my handloads are right in line with the mass produced stuff.

Yes, when I weigh the charges, they vary a bit. .1 to .2 grains, usually. My guns don't seem to care.

I'm not sure, but I assume that the factories are loading by volume, rather than weight, just like all of us whom use measures.

January 5, 2013, 11:43 PM
I use a Lee Auto-disk in my Hornady LNL. It meters Unique very well. It will even meter Green Dot within .2 grain.

I've noticed I can load up pistol ammo that performs better than I can shoot with a very inexpensive powder measure.

I have a close friend who is an excellent gun smith and has reloaded for over 66 years. He continues to use Unique powder in MANY MANY different rounds and finds it very reliable. He has had some containers of that powder stored for over a decade. He uses RCBS powder drops and has never complained about anything. He has a good supply of many differenct powders and still falls back on Unique. It and he has been around a long time.

January 6, 2013, 01:22 PM
I've used it with both LEE and Lyman powder throws to great success. Now I put it in a trickle over my manual scale, and it seems to dribble out pretty easy. When I was throwing it, variation seemed to be in the .1-..2 range, not enough to worry about for published data (I don't "tease the dragon" as my mentor describes it).

Of course I am not loading zillions of my 44 mag's here, just a box of 50 now and then.

It meters consistently in my RCBS Uniflow dispenser. I've never bothered to weigh the consistency of the loads it throws - my chronograph tells me its consistent. I use it for 9mm 124gr.

Good luck!

SlamFire1
January 6, 2013, 05:56 PM
Chronograph your loads. I have chronographed many of my Unique loads and compared the SD's and ES against AA#5, a ball powder, and Unique is as good or better. Bullseye always beats AA#5 even though the ball powders throw better.

GLOOB
January 7, 2013, 12:42 PM
One other thing to add. Since I load on a loading block, I have the chance to grossly verify my drops.

Knowing, as I do, the variation that I get from Unique, I have tried removing and rethrowing the 9mm charges that look high or low. Each time I did this, the new drop always looked the same. I gather that the ones that look slightly off are generally due to internal volume issues of the case, rather than a problem with the throw. The small variation in weight appears to be because of the powder density, itself. Not because it's messing up or clogging my powder measure. I can live with this small variation in charge weight. I have no plans to stop using Unique. It's my go-to powder for many of my pistol calibers, and it's my second-in-line for just about all of the others.

January 7, 2013, 02:54 PM
No problems with Unique -- the variations are within my shooting accuracy limits (not saying much there, so your results may require a tighter tolerance!).

After having variation with Unique in my Lee Perfect
Powder Measure I took someones advice and made
a dipper with a trimmed down 9mm case and a length
of bamboo skewer super glued on the side in the
extractor groove for a handle.

This thing drops +/- 0.1 all day long. Finally made
dippers for all my favorite loads. Don't have to worry
about keeping a hopper full. Guaranteed always on the
same setting you used previously. When you start
a new lot of powder though you need to "recalibrate"
it.

All the Best,

I've had no problems with Unique through my Pacific (a Division of Hornady) powder measure since the early '70s. It also does fine through my Dillon powder measures on my RL 550B and XL 650. As others do, I adjust, throw 8 - 10 and return them to the original container, adjust again, and check-weigh every 10th or so. I keep the resevoir around half-full.

As mentioned before with many powders volume is as important as weight. Been using high volumes of Unique for years. (+8 lbs year) It works great for me in all my meters. I found a really good deal on a huge lot of HP-38 so may be switching when the 1.3 kegs I have left in Unique run dry.

9mm, .38 Special and bigger I have no problems with. Loading up .32 Auto the charges are too small to get any consistancy so I use a LEE dipper that is very consistant.

On my RCBS uniflow I HAVE to make sure the measure is set up with the steel drum that has the smaller diameter hole when throwing small charges of flake pistol powder.

The large hole drum has caused problem when using small charges of pistol powder, wild fluctuations in powder weight (+/- .5 gr) and has even cause problems with powder bridging (no powder 1st round, double charge second round)
