Yup, the 3 inch magnums are a better choice, but I like the impact of the 12 ga slug better. Look at the difference in massive tissue disruption represented by the ballistics gel. Too each his own my friend.

I believe the 45-70 540 Hammerhead is even better with end to end penetration of coastal grizzlies in AK.

Can't find a ballistics gel of the Hammerhead, but here is a smaller 45-70 at over 1900 fps which is quite small and slow for many 45-70 loads.
