These two disciplines don't allow a single optic to do both ... that is unless your willing to shoot at 12x in rifle while others are at 16 ?
I’m new to the FT rangefinding technique. Does the rangefinding work better at higher magnification?
Absolutely ... as magnification INCREASES the optics DOF "depth of field" decreases. As the DOF decreases so does the range/distance a scopes parallax correction shrink. in distance.
Sadly scope manufactures set optics up for use in the POWDER BURNER world where the distances shot are at the low side within AG distances, but much more so further out.
While there are quite a few scopes that will parrilax focus down to 10 yards, there calibration MECHANICALLY is more biased towards the further distances than in close.
What this does, is ... let say said scopes SF/ parrilax has 360* of rotation, Many scope will have 10-55 yards only using 100-150* of this range available from 10 to infinity.
Where at times we get scopes that calibrate mechanically utilizing more rotation .. say 180 to 240* to cover the 10-55 distances.
In the FT game WE WANT MORE ROTATION which gives us better range estimation and separation markings once range distances get marked onto a larger SF wheel.
* Some scopes SNAP into and out of parrilax focus crisply while others are muddy and less definitive. Thus the on going search for the Holy grail of Hunter FT optics.
There a lot more to the equation of scope selection etc ... just hope this gives you insight you may not have been aware of or considered.
