Been shooting the Bob's since the 1960s and tried many loads over the years. The 115 grain Nosler Partition stands out in a combo of accuracy and bullet performance on Mule and Whitetail deer.
Loaded with 42-43 grains H4350 in two tang safety Ruger M77s 22" barrels I get 2820 - 2830 fps.
A Ruger 77 LT (long throat) shoots best with 45 grains H4350 at 2875 fps.
