i think by now the poor guy who asked the original question has to be ready to cancel his scope order and sell his guns.
i dont own a nightforce scope so i wont get into a debate over reticle choice. or for that matter scope choice.
one thing i am qualified to discuss is history, including long range hunting history.
i started hunting in north central pa. right after ww2.
at that time scopes of any kind were very rare on hunting rifles.
by the mid to late fifties some hunters in that area were using standard factory rifles like model 70 win. equipt with target type scopes like unertle, for shooting at deer at what was considered long distances.
there were no other scopes available for this purpose at that time.
varmit hunters were doing the same thing, and it was mainly that group who carried it over to deer hunting.
im sure many of them didnt realize that scope blocks must be spaced at 7.2" to attain 1/4 " clicks on their scopes. that was not common knowledge at that time.
most devised a click chart by actually shooting at various distances.
by the mid 70s when i became involved, unertle scopes were still the primary scope.
for calibers like the 6.5x300 wby. or the 7x300 wby. 75 clicks of elevation got you on at 1000 yds. depending on conditions, and of coarse location.
1 and 1/2 revolutions of the dial on a unertle and that was it.
from there the spotter took charge based on hits he saw on the ground.
lots of deer were killed using that system. and folks im here to tell you lots of em still are in that part of the world.
you are making this far more complicated than it needs to be.
a certain amount of elevation need be added to the scope for a given distance, on a given day. call it minits, meters, clicks or whatever, just add it and shoot. if you miss, adjust however you like and shoot again right now.
as for scope, there are quite a few good scopes available today for this type of use.
your success will have little to do with which one you choose to own.
20 years ago most of them were unheard of.
yet lots of animals were taken without them, and lots of them still are.
