Just wanting to know if anyone has reloaded 9.3x72r without the hard to find, expensive when you do proper dies. Bore is .366 ish. Im hoping/guessing that 9.3x57r dies work. First I'll be trying my .360 as dropped 358429 bullet powder coated to fatten it and 357 mag dies. If that's not satisfactory ill need something that will flare, seat and crimp the correct .367-.368 bullet.

Check out this thread on the subject. You can probably use .38-55WCF dies fairly easily. They are close to each other.

The book Cartridges of the world is your friend to learn about the old, obscure and often obsolete cartridges. It's why I like all the weird stuff.
 
The more I read these threads about odd ball calibers the more I realize I don't know much about firearms and such. At least three ongoing right now.
The real challenge for me was reloading the 11mm French Ordinance revolver. I ended up using .45 Schofield brass, shortened and thinned at the rim, then run through a tapered sizing die I made on a friend’s lathe from a .44WCF die set. The bullet I used was originally designed for the .45ACP, a 200gr LRN, .452” diameter, over 14gr of FFFg.

Even for its time the 11mm French was a weak sister but the guns made by MAS were way overbuilt. I bought the gun after seeing the first “Mummy” movie in ‘99. 🤣

I sold it in 2016 for close to four times what I paid for it. The die sets and brass I sold separately for too little.

The Handloaders Guide to Cartridge Conversions is also a good resource to have if you end up with an antique… or a few.
I've found a reprint of the book at that Ollie's store for $5, should have bought a bunch to give out to reloader friends I haven't been to the store in a few years but maybe I should stop in and see if there's more.
 
Just goto a machine shop & have them bore a piece of 7/8"14 TPI all thread to desired neck OD. Use a universal decapper & seat w any seater of same diameter.
 
Or just ream out a 357 magnum die set. That would be the cheapest, I think. Use the 357 sizer as a neck size only die. Recut the seater for the bore & grind a bit off the crimp Grove. What could possibly go wrong?

Well in the modern age its just as likely that someone has a cnc mini mill or lathe next to their 3d printer so it might just be that easy....

Never thought about the boring all thread. Sounds like it would work. A seater of same diameter could be pretty easy and affordably also
 
My advice is to do your homework before getting into oddball cartridges. Learned that lesson with 358 STA.

Getting set up to load it meant a $200 die set, Uber expensive 8mm Remington brass (which was available new) a fire forming process, and on and on.

Too much money and time.

If I were into 9.3x74R, I would buy as much ammo as possible when S&B does their runs every year.
