Shooting downhill increases one's effective range, a little. (I watched a friend shoot a mulie at over a 100 yards away. Down hill shot so that sort of changes the amount of drop. Wheelie bow. Perfect hit. I do not condone, btw. ) Downhill, 21 yards, my furthest, 11 yards closest, with arrows.
Norris is right. Woods, or mesquite and cacti thickets in AZ, make long range shooting difficult, and unnecessary. Set up and/or approach is key to getting close.
I would kill way more bucks (no does in AZ) if I could hit at 35, 40, but that is far with my primitive gear. Closer in, I agree, shot timing is key, and that is what I need more practice of than anything. Be capable with a second or so to act.
