12G OAL too long. Roll crimp advice?

[RMc]

Using a bevel crimp die to "finish" a roll crimp shotshell certainly enhances feeding in some cases.
For example, I found that 2.75" roll crimp #1B loads would not function in an old 2.75" chambered Winchester 1200. The same load, when run into a bevel crimp die after roll crimping would then function perfectly in that 1200.

Thanks Ralph. I'll look into that too!

the mec spindex kit comes with the crimp starter and the bevel if I recall and is not expensive about US$ 8 at titan reloading.

I apologise Tony but is there supposed to be a link in your post? I cant see one. Thank you.

Maybe a 2-ball load instead? I had good luck with that and still 1 1/2 oz of lead! I was using a different wad but perhaps a card in the bottom of the wad 1/2 diameter of a ball would help reduce height (and recoil) a bit....

That's worth a though too. Cheers!

The comparison of maximum load length for fold and roll crimps will shed some light on the subject of this discussion:

That's very interesting. Thank you for the information. My rolled cartridges seem to be just a whisker (0.010") under max OAL for rolled 3" in a smoothbore. Still, too long to cycle in my gun. It's a Turkish manufactured gun so perhaps that has something to do with it??

Personally I'd trim the hulls down just a tad, they will still roll crimp just as well and shortening them a tad should give you the clearance you need. My 930 semi-auto has no problem with them as crimped and the wife has an over/under. People have trimmed hulls down for years for fit for years, heck I have load data for 2 1/2" shells and shorter.
