Plenty of good stuff addressing your question. I have both rifles but have only grabbed the 270 WBY with 150 gr. Swift A Frames in the magazine. So far, all elk recovered and not one went very far. If you are questioning the magnification on the WBY, I would think it would also be a question on the 375. You can't go wrong but do not worry about the 270 WBY being too light. Hope to see pics....
