An awful lot of Alaskan moose die every year from 180 gr 30 cal bullets. I use the 300 win and 180 or 200 gr bullets - mostly partitions. But I don't hunt moster animals - almost pray I don't find one as they are SO MUCH WORK. But I don't feel under gunned. Sometimes I do wonder if a fatter bullet might be better.
But heck those triple shocks should penetrate very well especailly with the Wby.
Bear, your observation on that 180 partition is interesting - can you share more info - cartridge, distance, approx muzzle velocity?
The little moose I got this year was hit high behind the shoulder with a 180 X at about 30 yards; it clearly jolted and slowed the animal, which was trotting, but didn't stop it. Second shot was a 200 gr Speer hot core 40 yds maybe, a bit behind the ribs and angling forward; and dumped the moose in about 3 seconds. As I fired a third shot the moose dropped and I put a big nick in his nose. I really don't like shooting from a bobbing boat (motor off) but that was the opportunity and I took it. The first shot may have been enough but I wasn't going to wait for him to get into thick brush. Or, that was an old box of X bullets and I wonder if its performance was as good as the current production. I didn't do an autopsy to figure it out. That first shot made a noticebly different whack sound than the second shot that was a real solid Whump and the moose sagging.
