And I have .125" thick .412" and .430" circlefly cards.

And I have fine shot and round balls in .330, .350, .360, .375, .380, and .395.

And I have these .410 slugs (fury brand).

As for powders, most of the usual suspects.

Your thoughts ?

Thanks for that information. I have a single shot .410 that I was considering fireforming .303 British cases in. But my .410 will not close in the .303 rims.

Ray, those conicals look mighty deadly to me. I probably would not want to shoot them through a tight full choke, depending on their diameter, how soft they are and how they were loaded, but I would bet they would make serious deer medicine.

manual(s) drawings show rim dia. .514" (.444) vs. .540" (.303) with thicknesses same.

My CZ will NOT close on 444 cases... just to let ya know.

Yup, rim thickness is why they don't close in my gun. However having 2 MEC presses for 410 I just load thug slugs, OOO buck and shot in any 2.5 or 3" , no need to monkey with 444 brass.

Try a piece of 9.3 x 74R brass and see if it fits. Read it works well in making brass 410's.

When I was in High School I used to thin and resize the rims on 303 Brit cases for use in an Italian revolver a kid traded to me for a 22 rifle. We didn't know what cartridge it was (10 something millimeter) so I made it up as we went along. Its not difficult if you have access to a lathe. Doesn't need to be a big lathe. You could probably do it with a hand held drill and a belt sander if you have a steady hand and a good eye...

If I had 9.3x 74r brass I'd have a 9.3x74 rifle and wouldn't waste brass for a 410. When I have thousands of hulls .

Well, I tried a new, unsized starline .444 marlin case in 5 different break open actioned guns, a 1950s era bolt-action, and a 2015 mossberg pump and they all closed into ballery/lockup and extracted/ejected as the case may be. Only the rossi youth model combo (the one that comes with auxiliary .22 lr. and .243 barrels) showed some resistance to closing. I got serious with it and it reluctantly closed with a snick.
