How is it going fells. A spring Grizzly hunt may be lined up for me this year in AK a guy might be backing out of a per planed trip (unplanned baby on the way) and I will be sliding into his place not sure on any of the details yet as it would be my first trip to AK. Question is would any of you experienced bear hunters feel under gunned if possible with a .300 RUM for big bears as this is the biggest rifle I own. Would a 200gr Accubound backed by a full house of Retumbo at around 3200fps be adequate or should it be stepped up to a 220gr Partition or X bullet. I may be able to barrow a 375 H&H from a friend of a friend. But if not my RUM is it.
