Hengehold.
I and others have gotten excellent vertical shooting the 180 grain bullets with the 280 class cases and the 7mm SAUM as well as the Shehane. I can't speak to brass life for the others but I just got rid of some Shehane cases with at least 8 to 10 firings on them after one of the necks split. Some of the cases in this group were used in testing loads with velocities up to 3000 fps, but most of the firing was done in the 2900 range.
