I have a question I am hoping the forum can provide some guidance on. I am going on a float hunt for moose starting the 10th. A friend of mine is coming up from the lower 48 to join me. I order to save some of the hassle with the airline he is gong to leave his 7mm Rem at home and borrow a rifle from me. This is our first moose hunt and I am looking for a recommendation on caliber. I have a 300 WM that is my “Go To Gun” and we will be bringing her (Miss Jessica). I have several rifles to choose from but I have narrowed it to the following 7MM Rem or 375 H&H. This will be a rifle for him to shoot so familiarity is not an issue. We both know our limits and will not take a shot outside of 250 yds. Bullet construction is a mild factor because we both like Barns X and Nosler Partitions.
This is the question. What caliber would you choose and why?
