View Full Version : Anyone Make .350 Remington Magnum from 7MM Remington Magnum Cases?

I have a .350 Remington Magnum that I am thinking about pulling from the safe and shooting this Winter and next Spring with cast boolits. I only have about 100 rounds of .350 Remington Magnum Brass, and it looks like buying more is currently problematic. I note that the Parent Case for the .350 Remington Magnum is the 7MM Remington Magnum case.

Anyone have experience with converting 7MM Remington Magnum cases to .350 Remington Magnum?

I made a few for the rifle I had out of 338 win mag brass. I had to buy a neck turning tool and use it. Not a real troublesome project though.

There were a couple of long-running threads on forming the 6.5 and I think the .350 Rem Mag's a few years ago, well before this section was started. A search should still bring them up.

That's what happens to 7mm Mag range pickups, when I find them. :)

I use a .350 Rem trim die first, then a .350 Rem sizer. Sometimes I have to thin the neck walls, sometimes not. Depends on the brass, and your particular rifle.
