I heared from a woodleigh SP that failed in a 500 Schüler(Jeffery) on buffalo! Woodleigh bullets are not as hard as many people think they are! And the 9,3x64 Brenneke is if hot-loaded too fast for woodleigbullets at least on dangerous game. So i would take partitions or swift A-frame bullets. A very good choice woul be the CDP from RUAG or the TUG for your deer.
