Field Bag

So I been wanting to make a field or hunting bag. And I want some opinions, I was thinking of something like a 5.11 tactical rush 12, something kinda small not to big. I was thinking of putting an Omega 18 cubic foot tank, I have a Caldwell bag that’s about 6x4inches. I would carry my speed loaders, range finder and extra maverick mag o ring. Also Allen wrench set, flashlight, and knife. What y’all think. 
 
sounds good, whatever works for what you are doing, it will evolve as you go along .. this lightweight setup goes with me everywhere, got tools, orings, spare parts, hoses even a rifle barrel in the zippered top ..
