280 Rem Brass for 7mm Backcountry: A workaround idea


Fair bit of data here. Fella made his own dies originally, formed cases from 280 ackley as well. So it has steel and brass case data.


Edit........fair warning, the guys data is likely on the very warm side, he pushes stuff to the max in general. Finds pressure, drops charge 1% and runs it there 🤣 so be careful!
