Thanks for posting this video. I'll be purchasing this powder measure soon. I hand measured almost 3,000 rounds last winter and there's NO way I'm doing that again!! I've always wondered how accurate these powder measures were, and your video gives a great example. Thanks again!
I was just gifted a Uniflow from my brother. I saw your video first, and I must say you did a great job. Thank you for the great tips, like working the measure numerous times first, and also averaging over 10 charge drops. Very good tips, and one more thing. You have built a very nice looking loading bench, or counter top bench.
Got an rcbs reloading kit for Christmas. Everything went well until time to throw charges. Not much for instructions with this. I believe this video made it all come clear. Thanks!
Thanks. I have been loading for over ten years. Just now placed a bid on a Redding 10X powder drop. Been shooting a lot more with my pistols. Just tired of weighing every round. Thanks again for the check procedure.
38 years of using the Uni Flow measure gives me a little different method of averaging its accuracy. The lock ring and plunger are a little finicky to setup but once the charge is set the variance between loads can be < 0.1 grains with most powders. That variance has less single effect on consistent velocity than other factors such as neck tension, bullet seating, and case length. All factors work together to determine extreme spread and standard deviation of velocity.
I also have the same powder measure by RCBS but I would recommend to weigh 10 charges individually and see exactly what the variances are between throws instead of averaging them. I have found +/- of unto 1 grain. So I actually weigh every throw. For those new to reloading stay away from maximum loads unless you weigh each one.
Good Video, Thanks. I am just beginning to reload and you are the first that I have seen or heard give the suggestion of weighing 10 charges for the average. Thats nice and seems to be something I think will certainly help for the sake of consistency. Thanks again.
A buddy gave me the competition version of this measure. I tested it with Win 748 and it seems to be very consistent. WIth the extruded or stick powders like IMR 4064 or IMR 4895, not so much. With the extruded powders it binds up and chops the powder.
You'll find that issue with any volumetric powder measure, even the much more expensive Redding Competiton measure and even the Harrell, good as those higher end measures are. I just don't like the idea of physically sheering off my powder grains, so when I break out the can of IMR 4831 for my .30-06, out comes my RCBS Chargemaster. For all flake and ball powders, my 30+ year-old Uniflo is perfectly acceptable.
You must weigh many charges individually to find out how consistent your measure is. Batch weighing will only tell you if your measure is drifting higher or lower as you go along,.. It will rarely, if ever, tell you if you have a high degree of variance from one charge to the next unless you weigh many charges individually.
One thing I noticed is that the cylinder on your unit floor looks to be black I just recently got a Yuna flow but the cylinder on mine is definitely stainless steel but it also also a 1962 model and looks brand new I’m wondering if maybe you know anything about that like maybe it’s a model that is not made anymore?
@CheapChizzlinMooch Also kind of like what you do. I have been coming home, de-prime and tumble one night, then trim case length and prime the next and so forth. I like doing it that way best. Rather than doing 50-100 at a time all in the same sitting. I am not in a hurry so I just take my time and enjoy
i need a reloading stand or a way to clamp my press on my bench. I cant drill holes in the bench. any suggestions? seems you didnt like the frankford which just saved me the head ache
Try mounting the press on a piece of plywood & clamp ply wood to bench ( if bench is wife's Dinning room table put some cardboard between table and plywood )
JB I bought the Frankfort Arsenal reloading stand and have found it works perfectly. But then I don’t have a big bench like this and it allows me to move it around to anywhere I want. But I’m also reloading pistol not large rifle.
Thanks for the video - one thing I'd like to see would be what each of those ten weighed out to be.... I understand it's unlikely, but who knows if you've got 3 charges that were each 0.3 grains over, one that was 0.5 over, four that were 0.4 under, one that was 0.2 under, and one that was dead nuts... or something to that effect? My point being, while it's probably a good guess that it's within about 0.1 either way (total range of 0.2 grains) you don't know for sure without measuring. Also, 10 charges is statistically pretty shakey - maybe do 25 or 50 next time? I know it takes a while, and the video would be boring as all get out, but that stuff could be ran through in double or triple time. I'm just curious, I currently use a Chargemaster, and it's only good to 0.1 grains each way it says, but that is, from what I understand, more a description of it's ability to stop dead on - the scale is accurate to 0.1 grains, meaning a plus/minus of 0.5. I'd kind of be interested in going back to a powder measure, if I got a good beam scale or, even better, a great digital scale (0.02 grain accuracy).... but if the thrower only gets me within 0.2 or 0.3 a lot of the time, then I'm really not gaining anything. The idea behind going back to a thrower would be that I could trust the fact that it's going to be pretty close to dead on most of the time, so long as I do my part. Would mean being able to sell the Chargemaster and not deal with an electronic device for reloading.
powder throwers only vary weight by volume ... today's powder are extremely consistent in particle size and therfore conssistant in volume measuring devices... only variances in particle size can cause vloume inaccuracies.... so a good volume device will give consistent results with only +- .1 tenth grain error
Pardon my language but I FUCKEN HATE my Lee NOT SO PERFECT powder measure. I want to get this uni flow but can't justify spending just as much for this as I did my lee kit...AHHHHHHHHHHHH. Great vid, I'll see if I can ask the wife for one for Christmas....haha yeah right.
There are tons of Uniflo measures in excellent condition on sale on the Bay of E. Do you want to use crap equipment for your ammo, or do you want the good stuff?
Guys: I want to use this as a fast measuring tool for coffee powder (exactly 10g). is it possible to use this machine? will the powder (coffee) be too light for use? i
This is NOT how you check to see if each individual charge is correct. (Do not kid yourself. ) For those of you who don't know. However,..this IS a very good way to check for double charges.
Only a bench rest gun needs your type of accuracy ! Digital scales are not perfect and have the same tendency to drift + or _ .1 10th of a grain every now and again... So get off your high horse and and start your own channel....I see you don't have one which means you are just troling..... You can check every 3rd to 5th charge if you are paranoid about powder wieght on the beam before you load it.... After loading nearly 50 rounds and letting my hopper get low I was getting .2 grains light which was well within my loading data as I keep in the middle of the power scale.... I will say this....when loading at maximum velocity loads measure every charge! The differnece may be your current state of health or your gun's! If you are just plinking measuring every charge is usless... the hole in the paper won't be in smaller or larger if you are off by .1 tenth of a grain. The paper or watever target will be just as dead!
What say you now darkfinder? Ready to admit you were wrong? See my other videos under username DesertDX. I have lost access to the schleprock13 account for some reason. 73 es gud DX
Is it, though? Considering the many anti-gun rhetoric since that election, I bet you're eating your words now. Just because you liked the result of the election doesn't make it any less true.

Great vid, not only does the 5-0-5 seam to be very accurate, so does the thrower.
Glad thats what I purchesed!
Same results here!
Thank you for the video. I just inherited an RCBS Uniflow powder measure. Your video went a long ways in helping me use it!

That's a good powder thrower

Great video, would would you feel is a acceptable difference between loads and safe..
One thing I noticed is that the cylinder on your unit floor looks to be black I just recently got a Yuna flow but the cylinder on mine is definitely stainless steel but it also also a 1962 model and looks brand new I’m wondering if maybe you know anything about that like maybe it’s a model that is not made anymore?

just getting into re-loading, love the video
I would like to find a video with assembly and cleaning. I just got a old crusty one and am having trouble getting it apart for cleaning.
just go to rcbs site... just watched it and cleaned mine 2 days ago... works like new.... never lube!
does .1 make a big difference in velocity in a .222 .223 size case?
no
does the baffle help alot?
Nice, are you still doing single stage press?
Great video and love the rifle grenade ;)
You need to weigh each of the ten charges separately. Weighing them together allows the variances to cancel each other out.
i need a reloading stand or a way to clamp my press on my bench. I cant drill holes in the bench. any suggestions? seems you didnt like the frankford which just saved me the head ache
Try mounting the press on a piece of plywood & clamp ply wood to bench ( if bench is wife's Dinning room table put some cardboard between table and plywood )
I just cobbled one together with some scrap steel and a grinder and file and welded it in 2 minutes. I could not see paying $25.00 for a stand...

Uni flow Cylinder is what I was talking about yours appears to be black

get a used uniflow I did!
There are tons of Uniflo measures in excellent condition on sale on the Bay of E.
Do you want to use crap equipment for your ammo, or do you want the good stuff?
Guys: I want to use this as a fast measuring tool for coffee powder (exactly 10g). is it possible to use this machine? will the powder (coffee) be too light for use? i
only if powder is of uniform size...in consistent size results in varying weights
Excellent video.
nice vid!
Thanx much. Appreciate the Hep
Helpful. Thanks.
That thing has a nice design, but need some heavy automation.
If you're not doing 1200 rounds / minute, you're not doing a good job.
so much for accuracy
1 notch back from 250 grs is 245 grs ,,,,NOT 240.....

That doesn't sound quite like a metronome! You sped up and slowed down a few times!
"Opened after the election....I wonder why?" Incredibly inappropriate statement. Irresponsible language.
Is it, though?
Considering the many anti-gun rhetoric since that election, I bet you're eating your words now.
Just because you liked the result of the election doesn't make it any less true.
