Thought I'd post my findings on a subtension check I did on a Redfield Revolution 4-12x40 with the Accurange reticle.
I've had this scope on a few rifles, and while I have never been wild about the circle + dot reticle, it has held zero very well and doesn't change POI when power / magnification is changed. It's also compact and light.
Anyway I only checked what the subtensions on the reticle equal on 12x because that's what I use if I have a long range shot.
I shot the subtensions on a 4 odd foot high target with some old Core Lokt ammo at 125y.
Anyway a long story cut short is that the subtensions represented by the bottom part of the circle crossing the vertical is 2.2moa, the dot is 5.2moa and the junction of the duplex post and crosshair is 8.2moa.
Those subtensions will get me out to around 300, 400 and 500y. Having said that the "gaps" between the bottom two aiming points start to get a little too big to be useful. IOW the value of this reticle much beyond 400y starts to become a bit questionable.
Once I worked out the bottom point was near the 500y point I tried a few shots on a 10" high steel plate at 450y from the bench. Putting the top of the duplex post at the bottom of the plate at 450y got me three hits out of three shots. So with a known distance and time to calculate maybe its not the worst arrangement.
Sorry for the poor pics...
Anyway just sharing the drum.
I know, I KNOW... pass the FFs...
