Has anyone any experience of necking down .338 Norma brass to .300? I have a bag of Norma brass here I'd like to neck down if it is possible. Any advice would be much appreciated
I’ve necked down 338 Lapua to 308. Anneal, lots of lube, neck down. Then, expand, neck turn, and trim to OAL. I used sizing wax to neck down, then mobil one engine oil for neck turning.
Seems like a lot of work when you could probably just swap brass with someone.
Not that I don’t like cool projects… but setting up for a handful of brass that you can get off the shelf seems like lot of work! That could be expended doing other cool things!
