ACOG TA11H-308 BDC???

Is the BDC on the TA11E and TA11H-308 the same? I prefer the horseshoe dot of the TA11H-308 which appears to be calibrated for the M240 with a 21.7" barrel. I plan on using this scope on a SCAR-H with a 16.25" barrel. I will be using standard 147 grain M80 ammo with this combo. Should this reticle be adequate out to 800 meters?

Thanks
