I know I'm an alarmist...but I know a little of the grizz and the 7-08 is ok but You can probably handle the original 08...the 308...much better for moosies too. I hunt the elkies in grizz country and am going to carry a 300 H&H this year. Somebody actually gave me one!!
As far as prices...just buy something that is quality.. Savage 110 or one of it's derivatives will work
