You'd think J OC invented it?
6.7 Neuber (UBER), I like it.
I think 270 Uber sounds perfect.
Sorry, I couldn't help myself.
AFAIK the 270 Win was developed by/for Winchester and that made it a proprietary cartridge. I certainly have read the details about it development but can't recall them.
There are certainly those here who can supply all the historical details.
