    Tim,
    I've trimmed thousands of 5.56 pockets and I recently bought the Dillon Super Swage 600. I'll never trim another pocket crimp, ever. Once properly set up(you can over swage) this is so easy to use you will not believe it. There's a youtube video on how to do a very simple mod with rubber bands and string to make it even quicker by having the case
    locator rod move with the handle throw. I haven't done it as I don't mind lifting the rod manually.

    Swage. If only because you aren't removing metal. And I modified my Dillon swager.

    ATCtimmy, I just bought an RCBS bench swager and was a bit disappointed in it. I ran a batch of 5.56s thru it and when loading primers they still snagged on the edge of the crimp lip. Maybe it needs some adjustment (thought I had it set up pretty well), but I ended up using my chamfer tool to clean it out. Primers seated fine after that.

    I'd always used a Lyman pocket reamer and a chamfer tool in the past with no problems until I ran into WCC crimped 9mm cases. They are a bear to decrimp , so that's why I got the bench swager.

    What works best is what works best for you. I'm not giving up on the swager by any means, but it will have to better than now before I give up manually decrimping the pockets.

    You may also find the cases are long due to the military bullet crimp. I trimmed a significant amount off each case.

    Did you follow the youtube video or did you come up with your own mod? Either way I'd like to see what you did if you would be so kind. I like the idea but I'm not sure the mod I saw would be reliable.

    I have used the RCBS primer pocket swager for many years with good results.

    Sure. Here you go, fresh off the camera.

    This was based on the youtube vid mods. I used paracord instead of steel cable because it seems it would be less abrasive. I drilled holes for the spring and ran some self tapping (not self drilling) screws in for my posts. They only went in so far before tightening up, which was perfect. And it's mounted to an old 2x4 I had that already had a groove in it. Don't ever let anyone tell you you shouldn't hoard, lol. Then I ran screws into another 2x4 and fashioned a T so it would clamp in my vice easily. I swage after I trim, so clean up the case mouth with a deburring tool at the same time.

    eta: don't let those springs and fixture in the background throw you. that's my desklamp.

    Nice, I like the coil spring much more than the rubber band.

    I don't know much about the modifications, but I do like the way the swager arm goes over the base instead of to the side like the RCBS model.

    PAcanis,

    Thanks for the pics. I went ahead and did the mod like yours with the spring. It took about 15min. and I love it.

    Call me cheap. A counter-sink bit (about $5) on my cordless drill. I know it trims a bit of metal, but that hasn't been a problem.
