I have killed precisely one moose so my experience is limited.
I worked up a great .300 Savage load with the 180 gr TSX for my 99. United airlines sent my rifle to Toronto then Newark (neither are in Newfoundland). About all you can say it is it at least stayed on the same continent.
I shot the moose with a borrowed, rusty Rem 700 .30-06 that I had shot twice at a cardboard box at 100 yards. I picked out a half dozen rounds that looked the same from a gallon ziplock the outfitter handed me.
The moose died fine. My rifle showed up three days later and broken.
Suggest you try another method.
