I have the Storm book. That plus my ballistic calculator and actual DOPE is what I get my data from. Now a days I use my dope to build my own data card (home printouts) for each rifle, ammo range and distance.
Today at the CRC match I brought my book, opened it and used my home-made dope cards. Most everyone there has created the same type of thing. Lots of people build them, print them out, laminate them and attach them to there rifles or kit.
The TBAC bocck looks cool but seems to be only available for M118LR or a custom load for $45 extra. Thats seem like excessive and not super useful
