I use my Kestrel/Applied Ballistics for competition ($700 bucks). I use Bullet Drop + for the most part for hunting, load development and steel out to 1500 yards 95% of the time. It costs $1.99. It will go out to 2000 yards with 5 yard increments in inches, moa and mils. However I use 1000yd/50yd increments. It is very, very easy to use and adaptable compared all of the other ballistic programs I have tried. The only negative I have found is it works only with iPhones or iPads. Best $2.00 I've ever spent. It can keep all of your pet loads in the app.
Also there is a free version if you play around with it.
