My "shooting sticks" are my Edie Bauer hiking poles. I just put each strap loop over the other pole handle, place my rifle forearm on the crossed straps and take aim.
The hiking poles are adjustable for length if I need one or both poles lower.
When backpacking in my Browning A-Bolt rifle is strapped to the back of my pack. This way I can use my hiking poles for stability, push off uphill and to ease the strain on my knees on downhills.
All I need to do tobring my rifle around is reach behind me and release the QR buckle, pull the rifle down until the barrel clears its holding loop, swing the rifle around front and I'm ready to shoot.
I have greatly improved my Camelback Commander hunting pack by teh following mods:
1. cut off wimpy cloth belt and put an REI Ridgeline padded belt in behind the pack's lumbar pad
2. made an frame in the hydration compartment from 1" aluminum bar stock that I pre-curved to fit my back profile
3. had my shoemaker sew on 3/4" webbing straps and buckles to the pack bottom for strapping on a sleeping pad and roll-up deer sled
4. added aftermarket side pockets and a left belt pocket.
Now I have a pack for both hunting and backcountry skiing.
