I'm sure this has been talked about before, but here it goes anyways. I have been thinking about getting a 375 H&H. I already have a 338 WM and was going to get the 375 just for a big bear hunt. I just don't know if I really a 375 when I can load 250gr bullets in the 338 WM. Does the 375 really kill and penetrate that much better with say a 270gr bullet then a 338. Thanks in advance for your input.
