I understand where you are coming from, Bindi2, however my iron sighted hunting rifles are fully capable and have taken deer and moose to 200yards, which is my limit, for iron sights. Those shots were as easy as taking them with a scope, and perhaps taken more quickly as well.
.45/70 rolling block as well as 9.3x57 Husky.
When I was in my 20's or even up to about 35, I could do the matchstick deal with an iron sighted rifle (.50 cal MLoader).
The deer and moose were after that period of time. I did not need the precision of what you mention to cleanly kill both animals. Actually the deer was closer to 300yards. The 200yard shot on the moose was a chip shot - piece of cake. Boom/flap.
