A 30-30 will kill for sure ,, but at what range ,, and with what authority... I have shot moose in Northern Ontario at 250 yards .. a 30-30 I would not even think about it ,, and there is cuts up there that so big it would not matter what gun you have .. so a 30-30 is so out ranged;; you may get a close shot ,, but you have a long shot ,,, I lent a guy a 338 and he shot a moose,, i went too help him with it ,, He had shot threw a 3 to 4 inch popular tree and still killed the moose.. a 30-30 i doubt the result would have been the same .. every thing a 30-30 will do a bigger gun will do ,, So why would you limit your self ,, there is only one degree of dead ,, I would rather have massive meat damage ,, than too let the moose get into the rough stuff for sure.. I want him too fall as close as possible ,, I hit a moose in the front shoulder with a 338 and took him off his feet .. Something like 4000 lbs of energy .. I also went too help a guy that had shot a moose Calf with a 44-40,, He shot it in the neck and it fell right there ,, did not even step according too him ,, the bullet was two too three inches deep in the neck.. Lucky he even got it .. that 44-40 did not even have enough power too shot through the neck of a calf .. let alone a full size moose ... Had he shot it some where else I am SURE we would have been looking for it ,, 30-30 has killed a pile of moose for sure .. But i am sure the 30-30 has fed a pile of wolves and bear too .. At least if you do use a big gun you can not say i wish I had brought the 30-06 instead of the 30-30
