BPI- Super Crown Crimper- Is it a worthwhile upgrade?

While I think my crimps are generally very good (12 Ga, Rem STS hulls, 1 ounce #8) I was persuing a new copy of the BPI catalog and wondered if their Super Crown crimper in brass would be a good upgrade. They state it is very useful for new hulls but I have seen some comments that it works well for fired hulls also. Just chasing perfection...

Would be interested in anyone's experience with it.

Thanks

They will not auto-index properly to follow the existing crimp, so you would need to manually align the hull with the crimper by hand every time, otherwise the super crown would just form it's own crimp, and you'll end up with a 16 point crimp, then a 24 point crimp, ect. They are not for pre-fired hulls is the bottom line.

It would seem that with the rather common concern with crimps that someone would build something along the line of the old style MEC pre-crimp.... In today's world of CNC it would be do-able and would be a market out there... I have been looking for one of the old MEC for some while as a spare and walked into a store I have done business with for years..... "Hey, you have any old MEC stuff?", a couple minutes later I walked out with a new 8 pointk...... whooda thunk it?? Larry.

Never have I seen any better results using that metal precrimper. The plastic one is a lot easier to adjust in small increments as well. You can get crappy results using either of them.

Just relating my experience for what it is worth, I cringe anytime I see something once made of metal now made of plastic so I haunted E-bay for a LONG time before finally finding a metal pre-crimp die for my 20 ga. Mec. Changed it over expecting improvement and the plastic die laughed at me, I changed back to the plastic one, lesson learned.

The plastic Spindex seems to pick up the previous lines of crimp far better than the metal ones do. The nubs in the interior sidewall help that to occur. But if you are using a hull that has been squashed a bit, you better hand manipulate it back to some semblance of roundness or you might end up with what looks to be a 4 point crimp above a 4 point under crimp.

Different results for different folks is not uncommon. As long as I can continue to find what I need to run the metal I shall do so.... I went through the drill with the plastic, all the tricks, even now I have several with the 4 inner ridges cut out but I have them for backup only. I installed the metal some time ago and set it for the Nitro27. I now load (with no adjustments) GM, STS old and new style AA. Often with the Spindex when I set it for a tighter pre-crimp (I believe with the STS) I would find it traveling with the hull to the crimp station and having a big crash..... simply eliminating that issue is good enough for me.......
