I just found out I will be going on a guided trip to Alaska for bear next fall. I assume the guide will have a backup rifle in the 460 range, so I was thinking of taking my 30-378 loaded with 200 grain Barnes LRX. My favorite hunting load is pushing about 3200 fps. I'm just curious if anyone thinks this load will be sufficient. Should I try and borrow a larger caliber? Should I try out the 230 grain Berger OTMs?
