This is my single (on game) experience with Hammers. I shot an average 6x6 bull elk in Idaho at 315yds. The 181 Hammer was fired from a 30 Nosler and hit the bull broadside, high in the lungs. Admittedly not the best shot. The bull took a step or two and dropped in 10 seconds. In another 10 seconds the bull went still. The kill was caught on video through a 60x spotting scope.
I've got Hammers loaded up for 3 different cartridges this year and am anxious to see how they perform on other animals. In a few short weeks I'll be headed back to Newfoundland for another moose hunt. I've got the 236HH bullets shooting very well at 400yds when fired from my 338RUM @ 3,050 ft/sec. With a little luck I should have some good terminal info on this bullet.
Please post your results if tested on moose
