My max range kill was a nice Ohio 8pt at 42 yards. I've never felt comfortable enough with my skill level to shoot over 50 yards at an animal. I watched a 160"+ whitetail breeding a doe at 55 yards....too far for my skills. Felt like a pervert but all I could do was watch.
Been hunting with recurves and longbows for almost 45 years now and have been blessed over the years to take whitetail deer, turkey, bear and mule deer with my bow. All were under 20 yards, but have to admit I have been busted more times than I released and arrow.
Shot a 6x6 bull at 57 yards, quartering away, went through liver and hit off side lung. Ran 150 yards leaving a great blood trail and died in 20 to 30 seconds. I usually try to get in close to kill elk / deer, but this was a perfect situation and day 11 of a long tough hunt. Good times !
