Anyone know of a way to size the brass head on an already loaded round?

I ve got 2-3 boxes of loaded 410 ammo that doesn’t fit in chamber of my SA. It’s right at .476 on the brass and if I size it to .472 it functions well. I adjusted my Mec600 so it s sizing well now but unfortunately have as I mentioned 2-3 boxes loaded ammo needing slightly more sizing on brass.

Would like to size it without disassembling the rounds. This is a pretty easy procedure with loaded rifle ammo but haven’t ran into it on shotgun ammo. A collet or something similar would do the trick but not sure where to find such an animal.
Thx for any ideas or experiences.

Super sizer seems to be a solution. As mentioned more expensive than 2-3 boxes worth but gives me “ an idea” …. Friend has lathes ( builds rifles, etc) and I ll go see him and use the collet in the lathe to squeeze them with!

Hopefully works! Thx for suggestions guys ! 👍

Flyn Dutchman …. Guess what primers I m loading?? Chedditte!! I ll watch that, maybe use some CCI or WW , could be part of problem and not all sizing related! Thx

Just finished running 110 shells through the collet on my friends lathe. All chamber now, I checked each and everyone in my gun!!

Out of curiosity I measured the Cheddittes, WW and CCI primers. Didn’t have a mic but with my dial calipers both the chedditte and WW were .243 +/~ and the CCI was .240-.241. Primed 9 hulls with 3 of each primer….. Cheddittes took sized Rem brass head from .472 to .475…. Chambered but snug. WW only increased diameter to .473-.474 even though it and Chedditte are very similar sized primers. Thinking WW is a little softer, looks like aluminum vs steel cup.

CCI might have increased brass diameter .001 but hard to measure that close with dial calipers. Definitely the CCI primed hulls “fell” in the chamber much easier.

I ve never had this problem with 12,20 or 28. I guess an old dog (me) can even learn a new trick or two. Going to load CCI s in those Rem 410 hulls. Hope we start seeing some variety on the primer shelves soon. I ve got plenty Cheddittes but not many CCI for 410 loading!

All good info. Thx for the help guys!

HenryPeter, I ve only got 1 410 so hulls were shot in that gun, sized and when primed, swelled those Rem hulls where chambering was “no go”. It’s a SA so fit a little more critical for correct functioning.

Side note, my AAHS and Fed Top Gun hulls didn’t do this …..
