The trouble with a barbary hunt is when the animal hits the ground it always seems to be at least a couple miles from the nearest road and sometimes in some really nasty stuff. Ibex are even worse!
Here's my 2 cents.
I agree with jmden that the eberlestock
is great for carrying a rifle as long as you dont want to sit down, or carry a heavy load with the rifle in the scabbard. Its also hard to get the rifle out without taking the pack off. They put the load too far from your COG and the scabbard hangs down too far for me. Ive used a Badlands 2200 on nearly every hunt for quite a few years and really like it for single day outings because it does a lot of stuff well. It will easily carry a days water, food and clothing/gear, it carries a load well for its construction, it can carry a rifle behind the load and up high so you can still sit on a log and it does not weigh a ton to start out. My dad and brother in law both have Eberlestocks and I have traded packs with them on a few hunts just to see how the wore. The Badlands is far more comfortable and overall less bulky. Whatever pack you end up with, make sure it will do exactly what you want and fit your body correctly. Anything else will be wasted money in the long run. I am currently saving up for a Stone Glacier for a multi day pack, and who knows it may replace my Badlands for single day outings!
