Thats a good bear so matter which side of the border it came from.
Moose in southern BC and Aberta are Shiras also but not according to BandC. That said I have seen bulls near 60 inches west of Calgary back in the 70's and i suppose there still are.
Up in Northern BC the animals are much larger in body size. The same 60 inch rack will weigh much more.
Why not consider Alaska? Two guys can drive Montana to Alaska in 3 days, hunting should be good about anyplace. Maybe tow a small boat and hunt a large lake. Moose in general are easier than elk.
Good Luck
