Howdy:

The RCBS Uniflow powder measure made a believer outta me. No more "dip, trickle, & weigh" for production ammo.

Until this evening, I have soldiered on through load development and production runs with the Lee dippers, RCBS powder trickler, and RCBS 5-0-5 scale for powder handling. I was doing my reloading in stolen bits of time & never had time to set up my Uniflow powder measure.

Well, last week I finally got it assembled & ran my 3# of sacrificial Unique* through it to get its parts good & coated. Tonight I ran some graphite through it for, uh, good measure.

Then I got out my processed (cleaned, sized, belled, & primed) .357mag brass, Trail Boss, Lee Hand Press**, & went to town.

Within 10 throws, I had adjusted the Unflow for 4 grains of Trail Boss...and there it sat. I checked it every so often, chucking a charge into my 5-0-5's pan. These test throws were dead on. Every once in a while, the throw wouldn't feel right (gritty) & I would toss that one into the pan. It was usually a hair light & I would toss it back into the hopper.

I got 150 cartridges filled with powder, bullets seated, and taper crimped in a separate step in less time than it took me to dip, trickle, & weigh charges for 50 cartridges the old way.

It sure will be nice to shoot my Taurus Ti 651 snubby with mild .357mag fodder. My S&W 686 handles hot magnum load easily, but the Taurus is a handful with hot .357s.

My only problem: deciding whether to craft more .44mag/240grLSWC/Trail Boss loads for my wife's Rossi 92 carbine first, or load up some thumper .357mag/158grLSWC/2400 to feed my .357mag revolvers.



* For years before I started reloading, I accumulated tools & materials. I bought an ancient 3# can of Unique in a can with a 2400 label X'ed out. The powder inside LOOKS like Unique, but after reading some horror stories I will use no powder not in original containers & I will use no powder opened by anyone other than Yours, Truly.

** I own a Rock Chucker, but can rarely get to my bench in the garage to clamp it down & work. Too many other projects going on around the house. The Lee Hand Press allows me to process brass in little bits of time I manage to wrangle. The Lee Hand Press is just the ticket. I have delusions of finding the time & space for a progressive reloader some day.
 
jf,
I have used the Uniflow for about 30 years and have never had a problem with it. It just dumps the powder and keeps doing it accurately. With some extruded powders, I can sometimes feel a shearing crunch where it is cutting the powder. I just dump it back in the hopper and keep going.
 
In my experience.......

my Uniflow is OK. It cuts the heck out of Bullseye powder though. I just bought a cheapie Lee powder measure (27.00 versus about 60.00 for the Uniflow). I've only run 'Trail Boss' through the Lee, and it's not as sturdy as the Uniflow, but it does a great job. I'm thinking of just buying a Lee powder measure for each powder I load, and leaving it set up to save time.
I do NOT like RCBS dies (personal preference). Lee dies seem to be so much easier to set up, and their Factory Crimp dies are the best. Of course, all I reload is handgun ammo. RCBS may be much better for reloading for rifles.
 
Dip, trickle & weigh drove me out of handloading fifteen years ago after two days.
I finaly got back into it with a Redding 10X (pistol/small rifle only) measure.
Hodgdon Titegroup (flattened ball)meters perfectly. Never more than .05 grain off when doing batches of 50 primed cases (non progressive).
Clays (flake) isn't quite as nice, sometimes .1-.15 grains off.
I've been very curious about Trail Boss as I have an Encore .44 Rem Mag on order.
Thinking about Hornady swaged SWCHPs over a light powder for a plinker. I also ordered some vegetable fiber wads from Midway to put under the swaged bullets.
From what I've read, Trail Boss was developed with metering in mind, so I'm not suprised. Is it true that it smells a little nasty when fired?
 
Within 10 throws, I had adjusted the Unflow for 4 grains of Trail Boss...and there it sat.

Good for you. I needed to put a dab of Loctite on the threads of the adjustment screw to get it to stay in place.
 
My Uniflow has only had a couple problems in 8 years:
1) Power Pistol, when left in the hopper, etches the hopper so it is not trasparent.
2) 800X does not meter within +/- 20%
3) Blue Dot hangs up, and if I don't tap the nozzle with my finger nail, every forth or fifth round will be nearly a double charge.
4) IMR4895 requires 25 pounds of force on the handle, not 2.5 ounces like non stick powders.
 
I like my uniflow masure I have been useing it for about 20years with no major problems, for doing small runs when I cant get to my loading bench I like to use my hunington handheld press and a quinetics powder masure
the only thing I dont like about lee dies it the powder through expander sitcks in the case and jerks when it lets go (which I know they did on purpose to make sure all the powder drops through with out hanging up) but it is anoying when not using it as a powder die
 
I like my Uniflow for ball powders but for anything else I use my Belding & Mull Visible measure. I've had the B & M for over 30 years and only seen a couple of more since then.
 
I have a new Uniflow with the small metering insert. It throws 25 grains of H-335 ball powder very consistently. I am using the powder baffle.

I will be interested to see how well it will work with Bullseye, Power Pistol and H-110.
