Take A Knee, Sorry I got a bit sarcastic but I am a bit long in the tooth to believe in magic bullets that penetrate all the way through anything, at any distance, and destroy everything in between. Maybe I can't shoot as well as you but I have killed an awful lot of animals at both close range and at long range to believe that one bullet is best in all situations.
If you tell me that you chronographed the loads and know they were going X? fps and you saw the exit hole first hand I have no reason to doubt you. And I am quite sure you will never experience a failure if ever forced into a close range defensive situation with a grizzly.
