Throwing rifle powder charges

[creophus]

I'm considering an RCBS Uniflow. Should I go with this option or just use the Dillon powder measure to throw powder charges?

Right now I have W748, but would like to use other powders regardless of shape of the grains (flake, ball, extruded).

I use a Hornady drum-type powder measure on my 650, for loading bottleneck cases. Works similar to the RCBS Uniflo. I'd prefer either to the Dillon measure for that purpose.

:blues:The rotary drum-style measure cuts extruded powder batter, but I don't believe it throws a more accurate powder charge than the Dillon sliding bar measure.
It helps to slow the handle speed so that it takes about one second to move the bar from one side to the other, as this allows the powder to fall down the funnel, and not get pushed down by the powder behind it.
Ball powders should be within +/- .1-.2 grain, extruded within .2-.3 grain. I once pulled down and weighed 20 rounds of 7.62 Match M-118 ammo, found the powder was an extruded, probably 4895, and charges varied by +/- .7 grain. This was LC73 match. Bullet weight varied by over 3 grains. I know we can do better than that!

Ok, sounds like there might be some value in having it then.

Is it easier to work up a load? Personally I hate having to change the Dillon powder measure. Seems like the same problem of turn and weigh the charge is the only option to figure out how much powder you're throwing though.

Buy the Hornady powder measure, a copy of the RCBS Uniflow, with the micrometering insert. The sliding bar designs ain't got nothing on the rotary drums when it comes to loading rifle and for working up loads, the micrometer insert ROCKS!

[WalterGA]

Yeah, I got the micrometer insert. Forgot to mention, but you'll need to get the case-activated kit, also.

Yep, good point.

You're looking at $60 for the PM, $25 for the insert, and $40 for CAPD.

For rifle rounds, I load on a single stage. I throw a charge and use a powder trickler to get right on.

I have a Uniflow PM. Works wonderfully. Even long grain IMR4198 meters within .1gr. That's pretty much what I use it for. I use Varget for my rifles on my Dillon and haven't tried the IMR4198 yet.

[creophus]

So I'm guessing you just mount the PM to the bench, stick the case under it and turn the handle,then put the case back on the press and seat a bullet, etc?

[freakshow10mm]

Yes.

[creophus]

Cool, this might be a nice setup to use with my LCCTP. I'll save money by not using the Dillon conversion setup.

[freakshow10mm]

Oh, yeah, especially with the LCT. Dropping even a light charge of 22gr IMR4198 took a dual disk setup to drop at 11gr and I had to raise the case twice to get the correct charge, as it wouldn't go to 22gr.

I just took it out, charged it on the Uniflow after belling, then seated, crimped, etc. Little slower but not too bad.

How does the Redding 3BR or BR30 stack-up to the Uniflow?
