    I have a rcbs pp swage but it didn't open the crimp quite enough so I made new tapered punches with the big end just a bit bigger which fixed the problem. I also use a Sinclair carbide primer pocket uniformer chucked in my mini lathe which quickly makes very nice uniform pockets.

    Am reloading some once-fired GI -06 ammo for a chum. Primers all crimped in, so after resizing/de-capping, I ran them through an RCBS PP swager. On re-priming w/old Lee primer putter, some primers didn't want to go in - in fact, I ruined the Lee primer putter - put so much pressure on the lever that I stripped the threads that hold the case holder! On another, the primer wouldn't go in all the way,, and so the case was locked in the shell holder. Have it soaking in Kroil to kill the primer before knocking it out. By the way - miked the Tula primers, and they measured .2105 - the Alcans measured .2101/2. And the RCBS swage measured .205 - couldn't measure the top radius, just the shank. Did manage to prime (on the RCBS press) some, after using a PP reamer to clean up the PP's, but some gave problems still, whether Alcan or Tula. ***, Over?
    I find the RCBS along with other PP swagers to need a firm, positive crunch to accomplish
    Removing the crimp on many of the primer pockets.
    The crimp applied to the military primer can distort the pockets all the way to the bottom of the primer pocket distorting the walls of the pocket as well.
    Either another pass with the PP remover or use of a PP uniforming tool may be needed as well to salvage those cases.

    C&H has the only primer pocket swage that works.

    I haven't used one it may be the best , I couldn't say , but it's certainly not the only one that works .

    I have both of the RCBS swagers. The bench tool definitely works better but the one constant is you need to lube it or it just doesn't work very well, and for me, where most any lube is just fine for resizing brass, I find I really need a high quality lube like imperial for doing primer pockets. 2 passes is a definite plus as well, although lube makes a bigger difference than multiple passes.

    Just my personal experience.

    Primer pockets swagers are not designed to resize the entire primer pocket.
    They are only designed to iron out the crimp on the edge of the primer pocket.
    I have used the RCBS tool a lot and I find it works much better if you do 2 or 3 things.

    1. Use case sizing lube on it. Especially on the radius that rolls the crimp back.
    2. Pulse the pressure on the tool 3 to 5 times that is give it a full stroke then relax the pressure and give it another full stroke multiple times. This helps iron the crimp out and eliminates the spring back of the brass.
    3. Chamfer the edge of the primer pocket to help cut away part of the crimp.
