CoveJeepSXJ,
Happy to help! That sounds like what we call simply our Custom BDC Reticle. It would have been installed by our Custom Shop when the scope was built, or when it was sent in to have the reticle changed. It is typically designed for a 200yd zero and the value of those three holdovers would be based on a load described to our Custom Shop by the customer.
The dot above the center crosshair does not have a specific purpose in that scope, but you could play with it and use it as a range finding feature if you determine at what distance your intended game animal fits in the gap.
Give us a call at 1-800-LEUPOLD if you have any other questions about it!
