I'AM A 30 cAL. mAN ,SOI USE MY 30-06 WEATHERBY in everything I hunt, for a moose I would use as it already have being recommended the Federal Premium 180 Gr, Will do it.
Remember that it is Shot placement that kills ,not the size of the gun.
My cousin shot 1400 lbs Bison last year with a 270 and federal premium 125 Gr. The Guide at the Cheyene Sioux reservation in Pier S. Dakota thought he was nuts, one shot and the Bison was down, placed right in the heart.
