Update for everyone.. I've had a handful of days out this year. Lots of long hikes with my gear and I think I've got it relatively sorted.
A plate carrier has been working quite well. I get everything I need on it, and can have an almost empty backpack to haul out any game I get.
I did ditch the ranch hand while out with my rifle as some have suggested. Turn out you guys were right and it's extra I don't need.
The plate carrier holds:
Water bottle,
Binos,
SLR,
Calls,
Ear protection,
Bear spray,
Quick access knife,
cell phone,
Range Finder,
GPS,
All I have in my pack is:
shooting sticks,
first aid kit,
butchering kit,
rope and carabiners to hang game in a tree.
Works awesome. Everything I need is in easy access, and I don't have to make noise and shuffle to get anything out of my pack.
