What do you guys think would be a good rifle to take to Greenland. I will be hunting muskoxen and caribou. I have the option to take a 375 Ruger with 250 gr. TTSX. The 300 Ruger with 165gr. Interbonds or gmx. Akao a Ruger no.1 with 180 gr. Accurbond. Muskoxen can weigh up to 800 lbs. But caribou could be at longer ranges.
