I can get close to deer but to kill one at 800 yds would be way more than I could accomplish. I admit I am a hunter not a shooter. A 100-200 yd shot isn't a problem for me. Anything beyond that range would require me to develop some added expertise. I just never needed to develop that skill set and have no experience with it. My average rifle/ ML shot has been less than 75 yds over 55 years of hunting. I have many bow kills and all were within 35 yds with most being around 20. Even my late in life fascination with western hunting has taken all my elk at under 125 yds. Kudos to those who explore new horizons.
