Gorgeous moose, and great shooting! I'm impressed with that Hammer bullet! I've never shot a moose, or anything as "big". I have, however, shot a lot of Plains Game like Zebra and Wildebeast, Kudu and similar sized...tough thick skin, dense, muscled up critters. I liked the way the Barnes X and the old Winchester Failsafe worked for us. We never shot anything over 375yds though, and that was in Namibia. In South Africa ( northern Transvaal) my furthest shot was 150yds. I do think these kind of critters take a heavier conventional bullet or a mono of some type. I gave a missionary friend of mine over there a 30-06 with a bunch of the old Federal High Energy factory 180 Partitions ( they clocked at 2970 out of that 23" douglas barrel) He ran into trouble with Wildebeast ( only because the first shot was a bit too far back, then the "race was on", ha) and an Eland, both up close. He got both animals, eventually, but their thick skin had ripped that front off the Nosler "too early" and the shank just went through to other side, no exit, small wound channels. Don't you just love this kind of stuff? lol
