Cool! No, I didn't see that article on the .405 and Cape buff.

If twisted to shoot the 400's and regulates with them, they would be super, of course, matching or nearly matching the .450/400.

Those 300gr. factory loads should be way more than enough for any black bear.

Got some big fellows on Haida Gwaii (Queen Charlotte Islands) of BC.

I know of 2 that came close to or exceeded 800pounds, taken in the Juscatla region.
