Coues7 -
I too hunt Coues deer so I fully understand the need to trim weight and hike miles to escape the crowds. I'm curious though, my setup is almost the same as yours:
10x42 SLC 1lb - 12oz
15x56 SLC 2lbs - 15oz
80 mm HD Swaro 3lbs - 11oz
Carbon Tri 2lbs - 13oz
Badlands Pack 3lbs - 1oz
Rangefinder - 8oz
Camera(s) 2lbs - 0oz
Misc 3lbs - 0oz knife, game bags, rope, matches, first aid
Lunch 1lbs - 8oz
Clothes 3lbs - 0oz
Water 5lbs - 0oz
Total 29lbs - 4oz (if my math is correct)
Even with the rifle I'm still 10lbs lighter than your setup. Just curious what the difference could be??
In response to the orginal question...With coues being so small I don't believe you need a large bored magnum rifle - my current goto coues rifle is a factory 25-06. We've taken deer out to 460yards with it without any problems. I know people who will say that's not long range but for a animal the size of a coues deer it is certainly approaching it.
To extend my range though (and for the fun of it) I just built what I hope will prove to be a great medium (inside 550yards) to longrange (outside 550yards) coues rifle...total build - rifle, scope, bipod and sling came in at just under 10lbs. For coues deer I just can't make an argument that they need to be any heavier than that as long as you practice enough (a lot) to be accurate at the maxium range you believe you will ever need to shoot at and at a target smaller than your intended target.
I will tell you though for this years hunt the 19lbs I lost before the season made the 6 mile days feel like a walk in the park. Too bad I've put almost half of it back on.
BTW, that was a nice buck you took.
