Good luck, never been on one of those hunts, but they look like a lot of fun.
A desert bighorn ram hunt can be such an adventure. It was for me. Glassing all afternoon, learning how to see sheep, finding a Ram, watching it bed as the sun goes down.
Planning every detail of a stalk for the next morning. Getting up at 3am, hiking under the stars in a clear winter sky for hours. Beginning or making the entire assent under the cover of darkness or in a side rock chute out of sight.
Thermals are falling, perfect. Watching for first light, then wondering if I had done it all right.
On my first stalk I made one critical error and spooked a fine ram. I just stuck my head out alongside a boulder with no back cover. He was 150 yards away and ran like the devil himself was chasing him.
It is all about STEEP, STEEP and more STEEP. I trained for three months before my hunt. I was in my mid 50's then.
Nights were below freezing, days up to the mid 80's. We could never seem to carry enough water, always end up deeply thirsty.
My final successful stalk was long, over an hour, and my shot was just 125 yards. Used my Browning Safari grade bolt action rifle in 30-06 that i had for 30 years then. Now had it for over 50 years. Simple 3 to 9 variable Redfield scope.
Returned back to camp under a dark star filled sky just exhausted with a ram's head on top of my pack and my guide carrying the meat out.
I was a guide myself then too and was wise enough to hire a legendary sheep guide who knew this specific desert country and the wild sheep there.
