Another borderline difference between B&C and SCI is the Shiras moose.
B&C has always used the US/Canada border as the northern borderline for Shiras moose.
SCI put the northern borderline for Shiras moose somewhere in Canada so that moose from southern British Columbia and southern Alberta are scored as Shiras moose. I believe they did that because Shiras moose tags in the lower 48 are all on a very limited draw system, so many of their members couldn't just "buy" a Shiras moose for the SCI record book and various slams.
I believe the SCI boundary is the Bow River drainage in Alberta.
Rather than your SCI conspiracy theory, there is a very noted difference in size and confirmation of moose antlers between north and south of the Bow.
I agreed with this long before I became a SCI member. The 49th parrael is just a line drawn on a map and has no basis in the differences in the moose or moose habitat.
