If I was going to shoot a large Brown bear with a 44 magnum using a cast bullet I would want more weight than a 270 gr bullet, even if that meant slowing it down a bit which might even help the bullet work better.
If I was going to use a premium jacketed bullet on the same bear I would ask that bullet to do as advertised & stay together so I would give up the minor 20 grs & make velocity work for me because that bullet is a "premium" bullet, run that baby up there!
Mostly I would want more gun & bullet if I was serious about taking a large Brown bear, 45 Colt minimum & 480 better!
