I’ll start by mentioning that I first tried the SAC bushings for my wilson dies. SAC uses some different geometry in their bushings, which really made sense in my mind, and in practice made sense on the press. Just a sac bushing in my wilson die was enough to eliminate the doughnut on my brass. Unfortunately their bushings have been going quick and I was unable to get the size I really wanted, that and wanting a 6creed barrel for my next on my match gun made grabbing the modular sizing did easy.
Finally pulled it out and played with it. Nice packaging. Shipped quick. Had instructions.
Below is a picture of the bushing used in this die, different in that it sizes the neck along with bumps the shoulder. Really slick in that no doughnut is formed on the brass. It also allows some super fine tuning with shims, and the ability to use different calibers in the same die, ie 6creed, 25creed, 22creed. The bushing is polished and coated, as are their standard die bushings. Surface is very slick, and they don’t Gall annealed case necks like Redding or wilson have for me. I had a good idea what I needed being that my brass for this rifle is on its 8th loading. Edit I’ll mention that all sac bushings Iv used have been exactly .001 under what I used for Redding bushings. I think it’s due to the geometry, but something to keep in mind. I check all my neck tolerances with pin bushings to keep things the same, so a thou is immediately noticeable.
Screwed it into my mec marksman to touch and gave it a slight cam over. Started with my +.010 Redding shell holder, one slight adjustment on the cam over and I was there. Repeated on the rest of my 12 test pieces. The honing done on this die and bushing made sizing significantly easier than with my wilson FL sizer it replaced.
So that’s about it. I have a carbide mandrel coming in the mail from sac and am going to give that a go when it arrives. If I can eliminate a pull of the handle into my sinclair expander mandrel I’ll take that as a win.
Time to start cranking out some brass. July is a busy match month for me, it will have 500 pieces through it by the time July is over.
So far it’s everything I was hoping it would be.
