He has the money. If he shoots everything on the rack at his local store, one will shoot better and/or feel better to him. True story: I took a friend to buy a new bow years ago. He had just gotten a significant bonus check, so he was ready to splurge. He shot every one and the best for him...
Ta406, get a brace that prohibits any side to side torque. I found I can walk quite well that way with a sprained ankle......well, at least to a tolerable level of suck.
Elk bed on north slopes most of the time, at least in Colorado. Find beds, and escape routes. Watch the escape routes, preferably from more than 100 yds away. I've killed 14 elk off one ridge that way.
Hunt when you can, maybe during the week would lessen the pressure a bit. The water holes are still social spots for the bucks, whether there's water or not. Antelope hunting is fun, try to do as much of it as you can.
Have you heard of the Physically Challenged Bowhunters of America? You'd probably learn quite a bit from those folks. I would plan on bringing a couple of peanut butter and bacon sandwiches or something as you'll burn a lot of calories hiking. You need a knife, too.
Farthest about 3 miles. Worst was 2 miles in a heavy rain, two steps up, one step sliding back. And the downhill in the rain was treacherous. Of course, that was in my pre-Kifaru days so the pack broke halfway out on the first load.
Those would not work for me, a lefty. The LH bolt knob will hit the edge of the release button.
For me, it's a neoprene cover or one made from a tire tube.
I had the same problem last year with a 103 ELD-X out of a 6mm Creedmoor. One pronghorn, 100 yds, witnessed hit in the chest at 100yds, dropped, then got up and ran off. Never found her. 2nd one, 275 yds, penetrated about 4", recovered that one.
I won't use ELD-X bullets any more. Can't...
