Moose,
Excuse? Well, in that case, forget everything I said. You'll need at least two new rifles for those "goats". First, I'd go with either a 25-06 or a 270Win. Either of these should
take care of the short range stuff, maybe out to 150yds. Next, you'll need a 338Win.
Mag. for the long range stuff. And, some of 'em get pretty tough too, as noted by LuckyPunk. Yep, need that magnum for those big bucks. Heck, they can weigh up to
120lbs. On second thought, maybe a 375H&H. For sure, that ought to do.
