  • how do measure how much to take off?

  • @hardman476

    The guide rod that you insert into the case is case specific. You just insert it into the case and cut until no more shavings come off. At that point your case is at the correct length. The end of the guide rod has a pin that goes through the flash hole and stops on the face of the jaws.  The rod screws into the cutter. The case length is just the length of the rod between the tip of the rod and the shoulder where the cutting tool stops. Pretty simple setup.

  • Obvious burrs after chamfering at 0:38 and 0:54. Did you go back and fix those, or are those burrs acceptable?

  • @bobfre1

    Honestly I don't remember. I believe I used the cases as is. I am not sure what kind of effect this would have on accuracy. A burr might impact the concentric release of the bullet from the case neck during firing, but to what extend this will impact things on a larger level I wouldn't know. A burr might cause the bullet to hang up during seating and damage the case neck. I didn't notice this kind of thing.

  • Wish you would have shown how consistently the case length was cut. Thanks for the vid

  • @barnacle1brad

    Good point. I will measure a few next time I use the trimmer.

    I wouldn't worry about trimming a pistol case. For rifle cases they usually need a trim after one or two firings. Measure a few cases from the batch with some calipers to check length against the case specs.

  • Could someone help me out: when u resize with a die doesn't that trim the case also? Because people size then trim and it seems like a crap load of work... Plus u gotta debut and chamfer, clean and uniform the primer pocket and u still never added components to the damn thing so why do ppl trim also?

  • Great vid, good camera work too. Does the three jack chuck really make that much difference over the holder that comes with the unit?

    Also do you tumble before or after resizing? Or does it matter?

    Thanks

  • Nice high res video. Easy to see the details of the 3 jaw case holder. Thanks.
