I too shall thank all of you, as I need to work up some loads for my CZ 375---chris

The 375 is a snap to load for, I think it is inherently accurate in the first place...I use a lot of IMR-4064 and get great accuracy..and RL-15 has been good in some guns along with IMR and H-4350, H414, and IMR-4320..Mostly I load only 300 gr. bullets and my present English gun in that caliber shoots about any load to 1 inch at 100 yards and it shoots about all loads to the same POI..

O'Connor once said most any 375H&H will shoot all loads and weight bullets to the same POI, but that has certainly not been my experience, most won't do that, and they have shown a big spread between 270 gr. and 300 gr. bullets and most that I have owned gave me fits trying to get solids and softs to shoot to the same POI, but all were very accurate rifles...
