My 21 VR Trap gun has the same problem with shells fired in other guns. I have solved the problem by using my son-in-laws MEC Super Sizer on my reloads. https://www.mecoutdoors.com/super-sizer

If using a mec 600, I would try pushing the sizing collar down a little. Not enough to change the headspace but enough to possibly pull the diameter in. If its only .002, it might work. Not sure but worth a try.

I use my Super Sizer on all my reloads. I have collets in three gauges for it. I was wondering if it wouldn't reduce the rim diameter by a couple thousandths.
My SS also does double duty as a shell holder for turning roll crimps on my drill press. No need for any other type of shell holder to do that.
May God bless America and those who defend her.

Not sure but worth a try. The ring type sizers have the habit of pushing the brass head down toward the rim, where it effectively mushrooms the head, i.e. increases rim diameter. If you have a steady hand, a stone in a Dremel can be lightly run around the inside of the rim cut to gain you those few thousandths that you need. That said, as others have suggested, the MEC super sizer would be my first attempt to solve the problem

I did try adjusting the sizing collar down on my MEC 600 and it not did make a difference. I just need to ultimately switch over to the Cheddite hulls and for the time being figure out a way to remove the .002” on the AA’s.

If you start filing the rims on those cases, do you not run the risk of compromising the case and blowing a hole? That's folded steel or brass, and if the former, you will also encourage corrosion. It's a no brainer to hone the rim recess. It just isn't worth the trouble or risk of rupturing a case. But they are your eyeballs (hopefully safely behind glasses). 2201221208

I am not sure how removing .002” from the O.D. of the shell rim would compromise the integrity of the hull to cause it to rupture. Just curious as to your thought process, because if I am missing something, I sure would like to know.

Just curious as to your thought process, because if I am missing something, I sure would like to know. I just cut apart a cheddite that, at various points was as thin as 0.006". I question the feasibility of removing precisely 16.5% of that thickness and not more on a few hundred, used shotshells. Are they even that perfectly concentric and round to do this safely, and expediently to hundreds of shells? And who is to say that 0.05", if perfectly maintained, is enough. Afte rall, they aren't made that thin to begin with - possibly for a reason. After repeated reloading and possibly sketchy conditions that could add corrosion, maybe they won't stay safe, even if they began safe.

Turning down rim diameters on AA hulls just to be able to use them in one gun is too much sugar for a dime when there are other options, IMHO.
