I have a bunch of 357 mag brass and it needs trimming to uniform the crimp. Most of it is Winchester and the lengths are varied. I have an RCBS trim pro with the chamfer/reamer attachment which I have used with very marginal success. I have looked at the Lee Zip Trim and it looks promising but I would like to hear from people I trust. Successes? Failures?

I have found that LEE trimmers play loose with tolerances. I have gotten rid of all LEE trimmers and got a Lyman.Originally Posted by murf205

Plus 1, on both accounts.
Rights, and Privileges, are not synonymous. We have the Right to Bear Arms. As soon as the Government mandates firearm registration, and permiting, then that Right becomes a Privilege, and may be taken away at our Master's discretion.
I have had great success with the RCBS 3 way trimmer! Once you set it to the project at hand, it is very reliable for repeated case trimmings.
The entire reason to trim, other than the case being too long, is for uniformity of course but even though it is for a pistol, making the cases all the same lessen the frustration of crimp problems. I can get the length where it needs to be, it's the chamfering and reaming after that I am trying to make easier. I saw a you tube video on the Lee and it fell apart during the demonstration!

I use the lee cutter and lock stud for almost everything. Chuck the cutter into a drill press and it takes just a few seconds to trim a case. Not sure about the comment on tolerances of a metal insert rod. I get more variability with the lath type cutters depending on how hard I push.
