Thread: School me on the 7x57 mauser

I don't know what crap sources JD bases his opinions (or load data either for that matter) but it was called 275 Rigby as a marketing term nearly from the get go (or is this picture "fake news" too)



Dicko is a lot closer to the mark on safe and sane reloading expectations for it, it simply isn't designed to run at 65,000psi, and promoting loads running it at this level will eventually cause some poor bugger to have a disaster.
