Yea you can stretch it a bit by using a larger circle. Since the animals i hunt are larger I could use an 8-inch target and be in the vitals every time.
I have a serious dislike for large scopes with fancy turrets or ballistic reticles. They are fine for the range or maybe hunting from a tree stand but when your stalking or hunting out west or in the mountains they are a recipe for disaster. I've seen it so many times. Guys get flustered or dont have time to twist knobs....much easier to just throw the rifle up and shoot. Im convinced thats one reason hunters 40 years ago were better riflemen.
I've seen hunters that paid tens of thousands to hunt go home with nothing because they relied on turrets or ballistic reticles. Had a guy a couple years ago miss a bull moose at 100 yards. Found out later the scope turrets that stuck up 5 inches had rubbed against something hard enough to move them.
I could stretch it further but I see no point at this time my longest shot on game was around 125 yards lots of places I can't see much further
the scope on that 308 is a 2-7x32 with the Vortec BDC hash recital I could have easily zeroed at 218 and had more range built in , but 200 left me with things lining up on the recital at about the 250 , 350 marks. not that I have used them on anything but targets.
that said I can only think of one time in 17 years of running a 2-7 optic I zoomed in from 2x while hunting , that was a 90 yard threading the needle shot I could see the buck through the brush and trees but only had about a 2x3 foot opening without brush to shoot it through took a knee zoomed in to about 4x and watched my opening for it to walk into the sight that was with my 12ga in a slug zone
I zero the smooth bore slug gun with scope for 75 yards that makes it about 3 inches low at 100 and very close to point of aim at 25 and 50
one of the issues with modern society is people think they can buy performance and you can to a degree. if you buy a 1moa gun and you shoot 15moa standing it is still a 15moa gun standing.
maybe you use a tree for a rest and get that to 6moa , it is still no better than you are.
you can't buy your time behind the rifle , the experience of shooting it at different targets at different ranges in all sorts of weather , well you can pay for it in time and rounds , you can buy tools like ballistic calculators and range finders to shorten the learning curve some. but you can't plunk down the credit card and buy it right now no work involved.
you can't buy familiarity.
