For anyone living below 39°43′20″ N, I find the use of Cream of Wheat abhorrent for fire forming. Any self respecting resident living below 39°43′20″ N should use grits or corn meal (both dry, not wet) instead of the finely ground paste additive known as Cream of Wheat. Gil

Preach on brother, while I tap my foot.

I have used both grits and corn meal, pretty much because we didn't have that other stuff on hand. Now I pretty much always use worn polishing media, because it is handy and already paid for.
Stan, I replied to your answer to my PM but don't know if I sent it to you, can you check?

Received an email today from Barb Miller, Tom Armbrust's associate, that he will indeed test all-brass shotshells. One more small hurdle cleared.

Was blessed yesterday to receive a box of fired 9.3 X 74R brass in the mail, from a generous member here. Lo, and behold, they chambered in two of my .410 doubles! All the concern about thinning the rims were for naught. Onward we go. Next step, fireforming. I assume I should I use an OS card between the powder and grits?

I've just pointed the barrel up, trying not to spill any. At lower pressures, you may never have to worry about sizing. It may be possible to to just use a universal expander to get the mouth where you want it, and fire form with range loads? I'd maybe be mindful of splitting necks on the way up, good news on the project.

I suggest annealing the cases first.

A small wad of crumpled toilet paper should suffice between the powder and the grits.

What Parabola said, plus another 1/4 sheet of TP on top of the grits, so you don't have to sweep them up.

In fire forming I used a top layer of wax. It comes in sheets that are about 2mm thick. Just press the loaded shell into the wax and the case cut a perfect plug. It only needs to keep the contents in place.

I'm thinking I'll go to the river, park my boat, and shoot the grits over the river. I'd rather fish eat the swelled up grits than ants. I can see it now .....

I'm doing this 48 times. During this time a game warden pulls up. What are you shooting? Grits. Blank expression on GW's face. What? Yeah, shooting grits out of rifle cases to make them into shotgun cases. Silence. Is this how you bait up your carp hole? Blank expression on MY face.
