Thanks, MiG25. That's very interesting and informative. It would seem to bear directly on whether the 6.5x55 is sufficient for moose, and it would appear to be (if that were ever in doubt). It would be even better if cartridges, rather than calibers, were analyzed. For the 6.5 caliber, we can be pretty certain that the vast majority of these would be 6.5x55. For the 7.62, most would probably be 30-06, but a fair number could be lesser (in power) 30-calibers like the 308 Win. or other 30-caliber cartridges--30-40 Krag (with a number of Krag–Jørgensen rifles still in use in Scandinavia), 303 Brit., even 30-30. I'd love to see a 6.5x55 vs 30-06 comparison on number of shots on moose.
norway and sweden will be more now the 30-06 while finland will be more on the 308. you might get some numbers in contacting the env dept of those different countries or the global hunting associations.
