For a super-deep penetrating, expanding bullet, my 402 grain, plain base, Hollow Point cast bullets {wheelweights, not heat treated}, have performed excellently for me.
I have shot black bear, whitetails and large range cattle with them, and they have also performed very impressively in my test media {posted elsewhere}. This at a muzzle speed of 1640 fps and all shots on game at less than 100 yards.
I have NOT shot grizzly, but would not hesitate to with this combination.
Not sure how they would perform if driven to 1800-2000 fps.
I do not even know if this mold is still available from Lee. I do not think it was a big seller, as probably most folks think of a hollow point as a very frangible, shallow-penetrating bullet and are enamored with the current crop of square nose bullets for the .45-70. Those certainly have their place, but the Lee HP should in my opinion be looked at closely by those who want a bullet for bear or other heavy game.
