Re: rounds to take hunting
If it was a multiple big game species hunt, as in i had more than one tag in my pocket for deer, elk, bear, etc. I would be safe and bring at least a box (20) shells. It would better to have them and not need them than the other way around.
On the other hand if it was a backpacking hunting trip rather than a fly in hunt or outfitter drop camp. I'd make due with two magazines (10) shells. Figuring that if I shot anything I'd be headed back to the trailhead with a load of meat or two and I could stock up at the truck with heavy stuff like bullets and batteries.
