Has anyone tried fireforming 7STW from 300 H&H?
Not 7 STW but .30 LARA, which is basically a .30 STW improved. I used a Whidden hydraulic forming due. It is weird looking; will try to find a picture to share when I get home.Has anyone tried fireforming 7STW from 300 H&H?

Close enough.30 LARA- would that be a 30 Jarret? Or real close?
Keep us posted on your progress, I've been wanting to do this same thing with the belted basic brass.Fireforming belted Mag case is a petty easy thing to do. You can go up or down in neck size. Annealing afterwards would be advised after first fireforming. Also only bump back about .002" or so. Otherwise you get case separation at the belt after a few firing. Annealing helps stop the neck splits. After that, I only lost cases because of primer pocket giving up in 10 to 12 firing by annealing the cases. I would loose the cases in about 3 firing by FL sizing the cases after each time I fired them.
Here awhile back I got 150 straight tube belted mag cases from Peterson. I haven't found anything out there to get it done. I coming up with away to get them size down. The straight tube is to much, just to size down in one operation. I have a friend makes aircraft parts for every free country jets in the world. So I am going work over a Redding bushing die to accomplish it I think. Presently it's pie in the sky. I wrote to Redding and no reply. I have some extra bushing that can be turned to work on necking the case down.
In changing 280AI cases to 6mm/280AI cases, I had to do it in 4 steps, to achieve the reduced neck size. In down sizing the cases. I had or having to change the de-capping rod assemblies to allow the rod to fix inside the neck bushing. That required different Type S Decap Rod assemblies rod size and bushing ID sizes. Graf & Son had 2 of the three of those Decapping Rod Assemblies I have a 25/06 busing die on have to take that assemble to achieve what I needed. I also purchased 4-280AI Redding FL bushing die's. Once set up I don't have change anything inside the dies. There other steps that can be put in there too.
