Finally found brass that will hold up several loadings in the 338 rum. I annealed and turned the necks and they have proven to be very good. I have abused my practice ( load development) cases through 9 loadings now. My test have been at or above max with no primer pocket or swelling issues. Resizing is amazingly easy. No other brand has come close.

The options for 338 rum brass are limited so I gave there’s a try. So far I’m happy. I’ll lead by saying it isn’t beautiful. A couple hrs in a polisher and a quick neck chamfer it looks similar to a competitors brass you’d pay twice as much for. Weight from piece to piece is within my tolerance and it’s held up well to my first two loadings. Solid start for what seems to be bargain brass.
