I just received a hell of a birthday present, an XCR w/ a 18.5" barrel!!! I want to put an ACOG, specifically a TA31DOC. However, I think the bullet drop compensation will be "off", as the scope was tested using 55 grain ammo with a 20" barrel. I plan on using Hornady Tap 60 grain ammo, as I have a case of that stuff. I hate to drop $1600 on an ACOG and not have the BDC sighted properly. Does any one out there have any experience with this model? and if so, how far off is the BDC? Thanks for your help guys.

P.S.
I don't know sh*t about scopes.

I've got all the BDC data for the different ACOG reticles.

If you'll clock your bullet, and tell me what it is, I'll give you the 'best curve fit' or at least the data for whatever might match the best.
