First off it is all practice, confidence and limits. Know one can tell you how far you can or should shoot...only you can do that. If you have 5" groups free hand at 200 I wouldn't think twice of shooting 200 yards at a deer. Vitals are 7" on a typical deer, you also have the spine up top, not to rely on but it will drop them like now. A 3006 scoped will shoot effectively if the hunter is season and practiced to 300 yards or further no problems. With a 200 yard zero you'd be looking at approx. 7-10" drop at 300 depending on bullet, weight etc. Now if you feel confident only to 100 yards why sight in for 200?

Personally I sight in to be about bang on at 230 with my 7 Mag. I would shoot with the right conditions and deer out to 400 without batting an eye. Now you see here we don't consider anything 200 and under far, but normal. Pushing 300 is a good shot, 300-400 is a long shot and anything above is amazing or just pure luck. My furthest shot was just over 500 yards on coyote and I took out the heart.....PURE LUCK. On deer I have dropped one in the 350 range, skill baby all skill, yeah right. Now I do practice long range shooting, so I am fairly confident on 300 yards shots, but would never attempt anything over 250 without a solid rest or prone. If I can I will try and stalk closer, but sometimes it ain't possible. I have buddies who won't shoot unless the deer is 200 yards or so. Again all personal.

With a bow I am confident to 40 with the right conditions & shot opp. My longest kill was 35 yards. Average is around 20 yards. I practice out to 60 and find it really tightens my 30 yard groups...but would never attempt a shot on game at above 40.
