RCBS pocket uniformer ?

[06shooter]

I bought this to thread on a handle and work it by hand , ( large rifle by the way ) .
I noticed that Nosler and Winchester new brass for 3006 , the pockets are not consistent in depth.

I called Rcbs and they said the depth setting is .132"

Will this work for cci , fed , win etc.....
Would like a little more insight on this .

Thanks

Large rifle primer cups are ~0.12" high.*
The uniformer sets the pocket bottom to ~10-12 thousandths more that that to ensure proper clearance.
(More important, it squares up the pocket bottom edges.)

Since the uniformer references the base of the case, it works on any manufacturer's brass, and I've used (Lyman's) for all of the primer (FED/CCI/REM/WIN) I've got w/o issue.

Sure does. I've used it and CCI primers

Yes the depth setting of .132 is valid for all large rifle primers. One thing about the RCBS uniformer is that it has been said that it is adjustable, or maybe it used to be, and if taken out of initual adjustment is then difficult to return to its original setting. This would not be a good thing if the uniformer is being used for setting primer pocket depth. On that issue, kindly reply and advise if yours is adjustable or not.

There is a current thread, now towards the bottom of the list, titled Primer Pocket Brush, that has some information on uniformers. Check out posts 4, 10, 11, 12 and 13 for some additional insight.

Hey condor bravo , thanks for the reply.
Yes it has a set screw and I have not altered the setting , just made sure it was tight when I took it out of the package.

With calipers , it's hard to verify their depth setting.
I do know that the center point of the cutter is taller than the edge or cutting blades, which makes me think that it really doesn't cut to .132" .
I tried it on a winchester case and the best I could measure with the probe is .125 - .128.( on the primer pocket).

Sometimes I could get their .132" measuring the center point to the stop .

I don't want to cut too deep , I'll be using WLR primers and I do have some Fed. LR.
Thanks.

I use the RCBS uniformer the same way, The setting is pre set. I use it everytime I reload , cleans the pocket & seating is a breeze. I also clean the flash hole, debur from the inside only has to be done once. You should cut the pocket to the preset setting & bottom your primer. you woun't go to deep, primer should be lower then the base of the case.

I agree that using calipers is an iffy way to try to measure primer pocket depth. Just rely on the uniformer and allow it to cut to its maximum pre-set depth of .132. After the first cutting it can then be used as a primer pocket cleaner. Presumably the RCBS can be chucked into an electric drill for cutting and cleaning. I'm only personally familiar with the Redding uniformer tool that is non-adjustable.

I had the idea to use Hornady's body comparator to get exact measurement, (factory depth )

When you turn the rcbs uniformer upside down on a flat surface it becomes canted.

I zeroed the comparator , centered the cutter with the threads inside comparator, measurement = .756"

I moved it over (off center )on 2 blades and got .752" , so that's.004 " difference.

The body length on the cutter is .624
.752 - .624 = .128 " cutting depth.

The .756" - .624 = .132" center .

I think you will be just fine if you just go ahead and use it.
