Thread: Need help identifing brass

I got a bunch of brass that are exact dementions as a .357 mag but are longer by over .315 and cant figure out what they are. Anybody have any idea what they are?

Sounds like a .357 Maximum

Cool thanks I had never even heard of it before.

They should be headstamped 357 MAX. It's very similar to a stretched 357 Mag, except it has a thicker head and web due to the high pressures this round operates at. It wouldn't be a good idea to shorten them and use as a 357 Mag unless you carefully worked up from minimum because of the lesser case capacity.
