Looking for a tough 400 grain bullet to shoot out of my 45-70 guide gun. Something for close range black bear and moose or as a Brown Bear deterrent. I had been loading some 400 grain Beartooth bullets, but can no longer find them. Seems like none of the big manufacturers make the bullet I'm looking for. Anyone found a good bullet from a smaller company? Hoping to stay with the heavy bullet / moderate velocity theory. Don't want to drop to the 350 grain unless I can't find the 400.
