Recently reviewed the .458 Barnes TSX copper bullet @ 300 grs.
While it might do for deer or smaller-it is NOT a bear bullet in
a 450 Alaskan or any 45-70 for grizzly. A 350 gr is minimum, and 400 gr bonded- core
like the Woodleigh or Alaska Bullet works is the safety first choice.
Harold Johnson complained of the way
standard 348 Silvertip bullets blew up on heavy bear
covered in thick fur and ice. So its well-constructed bullets in
rifles made for the big bear.
