I have 2 older 35's Rem. 141 pump and Rem. 760 pump, they're great for deer, hogs and blk. bear. Will it harvest a Moose yes but you need to get up 150 yards for these old punkin chunkers to do thier best work. You would be better off with a cartridge that shoots flatter with good bullets. 6.5x55- 270- 06- any mags, if recoil doesn't bother you.[&:]
