Have had several emails wanting my 350 gr. load information for the 375 H&H:

66 grs. of IMR-4895 (H is interchangable)

68.5 grs. RL-15

72 grs. of H4350

76 grs. of H4831

71 grs. of H414

All worked OK with Woodlieghs but the long Rhino bullet required the IMR-4895 gr. load...

My gun chose the IMR-4895 and RL-15 loads.
