This is one round that I recovered from the grizz I shot this year. Hit it twice and the other bullet blew thru. This round was found just under the skin while skinning. I shot the grizz at 60 yards with a 300 win mag 180 gr federal premium nosler accubond. The first hit was slightly quartering away and the bear went ballistic. I shot twice more trying to hit this bear and must of missed once. The bear was down and dead within 15 seconds or so.
I wouldn't expect this from an accubond but is this from shooting so close? I'm not a guru on this stuff.
