First, those complaining about no upgrades dont have a clue what theyre talking about. I have upgraded at least 5 times at no charge. They are continually improving this great program (for free). The other version of the program is really for a different use. (I dont know about you, but I hate reviews from people who dont read the app description and then give a bad review when it doesnt do what they THOUGHT it did.) If youre a hunter or typical target shooter THIS APP IS EXCELLENT! It has a HUGE library of factory ammo loads, not to mention the projectile library. I tested many types of ammo in my .270, and Ive got several different loads saved reflecting the differences in point of impact. No matter which ammo I take with me I have a handy reference to its down range performance.
