You have a faster drop with the 300 AAC, but you can still use that TA31 with it. Just zero and afetr a little time and some rounds down range you'll be able to put some dope together at where your holdovers will be yardage wise. Wont be too far off and a quick adjust on the fly will dot it if need be. I don't know exact, but at 200 yards you might be 3''-4'' difference from 223 to 300 AAC. Someone might want to check that, been a long day here...

I don’t know enough about 300 BLK ballistics yet to give you an firm answer, but I’m sure it’s not going to be calibrated regardless if you are using a 5.56 or .308 ACOG. Both those units are calibrated for a specific ammunition/bullet weight/ velocity.

A ballistic calculator like Ballistics FTE can get you those answers pretty fast if you have a 300 BLK chrono results from your rifle.

You are basically going to have to re-learn and remember new holdovers when using either of those optics.

I doubt the 7.62 nato hold overs will be of any use either. Just DOPE it the old fashioned way and work out your owner hold overs
