shopping for the rcbs trim mate and accessory .. midway has large pistol .. large rifle and small ..
is there a diff in large rifle n large pistol ? first i seen this selection ... @meketrefe

Hi,
yes the large rifle is about 8 thousands taller on average than the large pistol. Also 4 to 5 thousands wider.
This doesn't mean that it could not be used in certain cases given they are on the extremes but it is not
recommended and one would have to be very careful.
One would have a big problem stuffing a large rifle primer in most pistol cases.
At the other hand the pistol might be too deep in a rifle case but with the right cases, firing pin and or seating
process one could use them. Again not recommended.

wtih small primers is easier to exchange as they have compatible dimensions.

RCBS Trim Mate Case Prep Center Carbide Primer Pocket Uniformer

so i would need one of each then

do you? What are you trying to do? you also have the hornady cutter that is 1/2 the price of RCBS.

I agree there is nothing like automation and preppign cases is a royal PITA.
but one thing is cleaning the pockets and another is trimming.
The wire brushes for the trimmer are cheap and if you want to trim the hornady should work
in the RCBS trimmer station too as I think they share the same thread. we have to veriy
this is the one.

But other than swagging primers for military cases or cutting off the crimp don't think you will
need the uniformer a lot. Most cases winchester, FC, hornday are pretty consistent these days.
for cleaning just the actual pocket brusshes are good and not too expensive like other RCBS parts...

a drill press is a good way to do the lee trimmer if that is what you use.
Can even build an oversize cam for the rotating piece in the shell holdder so it is easier to
move in and out quickly.

I don't use lee with a few exceptions. I use the foster 3 way trimmer that gives the best 3 way
cut and fastest way to prepare brass w/o getting tired and match consistency in the cuts.

But whatever formula as soon as you use mechanized will save you some serious pain in the hands.

I personally do not uniform/clean pistol primer pockets. I will however clean bullseye pistol ammo primer pockets with the wire brush head.

I uniform all match rifle rifle case primer pockets.

I've been using this Lyman case prep center for a while now. I bought it mainly because the vast majority of my rifle ammo is 5.56mm, so cleaning out the primer crimp to reload was a major PITA. This case prep station made things so much easier.

Hi,
I don't think you need pocket uniformer and with 270 you will not have military crimps but if you simply flare
the pockets a little more the priming will be so much easier to start the primers into the primer pocket.

for that you can just put the primer pocket in the chamfering cutter for 3 seconds or so or buy the actual
military cutter that will put a flare on the pocket at teh same time that cuts the crimp away.

The RCBS is a nice station. Mine has been running for many years w/o much rest and still running like day one.
But for the actual trimming I mostly use the forster 3 way cutter with the long shaft.
The trimmer is not that expensive and can even be found in ebay preowned and if you are going to use
the 3 way heads anyway then it is not that important if the original cutters are new.

This is the fastest way to get the best possible cut and there is no need for deburring or chamfering after.
The consistency is amazing. I am suggesting because I have tried it all.

this is the forster system. A lot more consistent than the 3way RCBS...

People install their own power units like a drill with the shaft adapter and design their own
jigs for helping wiht the task. This is a bit like mine but mine is faster and easier because the power
source is stationary and the thing that moves is the actual trimmer so at the same time I put the
case down I can push it with the left hand and in 2 seconds I have a case trimmer, deburred and chamfered
with spreads around 1 thousand.

Damn, drill press...never even thought of that.

I use the old hand held 18v.

I think the press makes it easier. and making the base is simple with a hex holder/shaft and a piece
of wood like 2x4. For the cam part that rotates and in order to have more leverage you could find
a pipe gasket holder or something even cast a piece with epoxy or simply find a collar with a set screw that will increase the diameter and then it is easier to rotate.

Just remember wiht the drill press you need barely any pressure can do it with the pinky finger
otherwise you might screw up the pilot. Just need to slightly touch.
There is a lot more leverage than with the hand drill that is for sure.

If you put the pilot and cutter at the bottom and the holder in the chuck then you will not have to worry
about shavings falling inside the case and in the holder and making even contact with the holder
and stop potentially difficult.

I don't use the lee a lot but I have some calibers I still use since they are smaller quantities yet
still I always use power. my hands have taken enough abuse in my life already.

I found this video... this is just lazy and making a proper support is easy.
The nice thing about the lee is that the pilot gives consistent cuts something that one
could not achieve with the drill press w/o a stop because it is not a substitute for a precision
trimmer or mini lathe in terms of precision.

If I get a chance I will make a quick video of my trimming stations.
