You can't go wrong with 180-200 gr partitions backed by max loads of RL-22 or IMR-4350. I've used 200 grain partitions in both a 300 WM and 300 RUM and never caught a bullet. I've caught one 200gr Accubond from my 300 WM as well as one 165gr GMX. Both went through about 3-4 feet of elk before stopping in the hide.
