Technology has changed and both Brown dog and 4ked horn have written computer programs that will print out custom paste on BDCs.
You just run your ballistics program and get your drops and then use sideways printing with a small font in either MS Word or excell and print it on to a sticky label and paste it on your target turrets. When you change loads or decide to hunt in a different elevation such as Death Valley you just make yourself a new label and stick it on the target turrets. In theory it is just as accurate a method as the old 3X56 cards or the cheat sheet on the stock.

If they have something to replace word, I'll send them money today. What do you me written computer programs?
Nothing new about MS word, excell or printers. Toting a printer to hunting camp with stickly labels is not generally a viable option. What if pressure/temp changes from printout time (night before) and the following evening when you see the nice bull at 1137 yards?
Nothing really compares to a pocket PC with Exbal, my NF scope with NP-R2 illum reticules and lines every 2 MOA, a quality long range hammer (I have a few from Kirby), lots of practice/experience (I need more of). What I find far absolutely absurd is the pinned Ballistics Programs (Web based & Down-loadable)
- Even the pocket PC version is just a table that needs an internet connection to download the data. Who has an internet connection at elk camp?
I can't see the advantage a BDC has over say my Kirby/Lilja/338 RUM shooting a 300gr MK out the 30" tube, my NF 5.5-22x50mm SCOPE sighted dead on at 550 yards, ExBal
, pocketPC, two wind meters, temp gauge, Harris BP, good bino's, patience. I only need dial in a correction c where -2 < c < 2 MOA ; if I use my NF BR, I can get down to 1/8 MOA corrections. Can you do that with 8pt Tahamo? It does sound like a far superior approach to the old fashoned static BCD, but still not the ultimate choice (and you have to pay more for it).
