I have an IOR 1.1-4 scope with the M-Series CQB reticle that states
This reticule features 15 mils of ranging or holdover and has a center dot of 1 moa. Inside horseshoe is 10 moa and outside is 18 moa. A 10" target ranges as follows. 100 m inside horseshoe, 200 m dot to inside edge, 300 is first circle marked "3", 4 5 6 are the smaller circles as you move to the right. These scopes are true bdc cam for either .223 or .308. Red illumination.
If I zero at 50 yards I am trying to gauge my hold overs for this at 100, 200 and 300..any idea's, my thoughts are up to 300 yards as long as I keep the target centered in the horseshoe I should be good to go, looking at dinging steel and punching paper not bench rest shooting..
I think I actually answered my own question, I called IOR and the turrets are in 1/2 MOA adjustments so I plugged in my current load to the iSnipe program and my settings with a 50 yard zero would be
@ 100 Yards down .52 MOA ~ .151 MIL
@ 200 Yards up .8 MOA ~ .233 MIL
@ 300 Yards up 3 MOA ~ .873 MIL
So my initial assumption of keeping it within the donut should be good to go..
