Finally, the last piece of hard-to-find documentation for the Mk12 deployment kit is available! These are new production ballistic data cards sourced directly from Ballisticard Systems, made using the same original files and manufacturing methods used when they were initially printed for the military. Each of the 3 revisions were issued at varying stages of the Mk12 development cycle as ammunition changed and more ballistic data was collected. The Delta2 cards were commonly seen with the SPR (pre-Mk12 designation), and early Mk12 Mod 0's. Later, the first DeltaMax card was used with Mk12 Mod 0 and Mk12 1 builds. Finally the later revision DeltaMax card was included with later built Mk12 Mod 1's through the end of their service period. All that said, there is no hard and fast rule, cards were likely reused, swapped, or even missing. This is only a general recommendation based on the copyright date and some photos as seen in the field.
The front of the card contains ballistic data while the back contains useful field information for estimating leads and environmental factors. Also included is a set of instructions from the manufacturer on proper use.
NOTE I: Each order will come with 2 Ballisticards and a set of instructions. Per the MFG, the second card is a backup in case the first is damaged/destroyed/lost.
NOTE II: These cards were designed specifically around the exact ammunition type and barrel length listed on the front. Using different ammunition manufacturers, updated loadings, different barrel lengths, etc. will yield different ballistic solutions than what is printed on the card.
Ballisticards is only a one-man operation any more. He's retired and very much enjoying it. He was very generous in restarting production of these cards so we collectors could enjoy them. PLEASE DO NOT ATTEMPT TO CONTACT BALLISTICARDS ABOUT PURCHASING, HE WILL NOT FULFILL INDIVIUDAL ORDERS. I will continue to resupply as needed. Let the man enjoy his retirement please!
