Only moose I saw shot with a 270 I think was with Rem. Corelokts. I would go with the 160 Nosler as I think it is a classic. The 160 and 175 Partitions in 7mm worked great so the 160 in 270 should too.
Behind the shoulder almost anything would work but moose bones are massive and deserving of a premium bullet. The Trophy Bonded are very good too. The TSX when driven fast are excellent, this is the only one I would drop down to a 130 grain bullet. The others I would go 150 or 160 just because moose are big. Hosea Sarber an early Alaskan Game Warden liked to use the 170 grain Barnes original for moose and bear. These were cup and core with a thick copper tubing jacket.
Would that be behind the front shoulder or...
