I have the red chevron reticle in my ACOG TA11F, with bdc to 800 yds. Does anyone have the increments of drop between each stadia? MOA or inches. I'm shooting a 16" barrel/flat-top .223 with various off the shelf rounds. Obviously not what it the reticle was calibrated for, but if I can find the drop values at each mark, I believe I can build a load to coincide rather closely...hopefully!
 
Re: TA11F reticle question

Received this answer from another site, just in case anyone is interested in the future.


The TA11F BDC is calibrated for M855 traveling at 2,970fps with a BC of .304 and a height over bore of 2.5".

According to JBM Ballistics, the inches and MOA drop with that information in standard atmosphere respectively is:

100: 0 inches, 0 MOA
200: 2.4 inches, 1.5 MOA
300: 11.1 inches, 3.5 MOA
400: 27.8 inches, 6.6 MOA
500: 54.7 inches, 10.5 MOA
600: 95.2 inches, 15.1 MOA
700: 153.3 inches, 20.9 MOA
800: 234.3 inches, 28.0 MOA
