Observed/involved with the autopsies of 3 bull moose last fall, 2 taken with factory loaded 180 gr Trophy Bonded out of 300 Win Mags. Both moose were shot at about 200 yards. 4 of 5 bullets were recovered, all under the skin on the far side, all mushroomed just like the ads, including one that went thru a shoulder.
I took my moose with 150 gr Partitions out of a 300 Savage, at 65 yards. Both bullets were recovered, same story as above.
Bull moose #4 at that camp, was taken with a single 180 gr Partition out of a 300 Win Mag, thru the lungs. Complete pass thru at about 200 yards.
The hunt was in Newfoundland.
