Cal's .600 NE was brutal even with being heavier, the .577 NE only slightly less so.
His DB 4 bore slightly less so due to the weight but I needed the support of sticks to hold it up
My own DB H&H 8 bore is relatively mild in comparison
Still well worth the trip to Alaska for such shooting, as there is probably nowhere in the world where I could shoot these supreme rifles
