No real world experience - here and in most of Canada it doesn't meet the caliber minimum for big game (I know it does there). Did you sell your MH? Or are you just keen to give the MV a try? Haven't been to Haida Gwai in a long time, from what I remember the deer are roughly the size of a German shepherd, correct?
I would suppose any hunting ammo would work although I would lean towards a 60gr partition, 62gr fusion, a federal blue box soft point, or even a TTSX. Me personally, I wouldn't use varmint ammo as I would be worried about bullet failure leading to inadequate penetration if the shoulder was struck directly for an example. I think the federal MSR line uses the fusion bullets and is supposed to be pretty reasonably priced. As I said, any of the 'premium' bullets designed for weight retention AND expansion over varmint ammo. FMJ's are of course NOT a good idea, so if you can't find any of the premium stuff I'd go for good old federal blue box or Remington core-lokt in a heavier weight bullet ~60 gr. As I recall, ATRS does not recommend lead tipped bullets as there can be feeding issues so testfire before you go of course.
Of course, if you still have your MH throw a red dot on your 308 or 6.5CM and you're golden! Hopefully a Canadian with real world experience can chip in.
