I think I might have a handful of live 7mm STW rounds… I’ll try to get out to the ammo stash this evening and check.. if they’re out there you are welcome to turn them into once fired brass
I'll help a guy out whenever I can, but I only have 30pc. I need to hang on to them to use for my display boards.
There is some belted magnum basic (straight wall, no headstamp) brass on Gunbroker you could try. I think there would be a problem with the necks folding in on themselves trying to squeeze them down to 7mm. I've only used them for 450 Watts, 450 Ackley and 470 Capstick.
Your best bet would probably be necking down 8mm Rem Mag.
I've had 3 7mm STWs and couldn't develop a load that would shoot under 1.75" in any of them. I think the barrels were too skinny. The only one I have left is on the chopping block scheduled to become a 404 Jeffery.
Good Luck with your search

I checked my stash of odd ball ammo.. it looks like I have 5 rounds of factory federal ammo and 1 round of winchester fail safe factory ammo...
its not much... but if anyone needs 7MM STW, let me know.. Im happy to box these 6 rounds up and send them your way (if nothing else its range fodder and 6 pieces of once fired brass once you squeeze the trigger on them to do whatever you please with)...
