I have it. The loading data is literally just PDFs of the stuff you can get off the websites.
The loading 'program' is just access databases. I do use it, mainly cause I can barely read my own handwriting, and I am horrible with Access and Excel. The calculator programs are neat too, alot of them are out there on the web, but nice to have them right there.
So, for the 12 bucks, it's well worth it. But it is not like a ballistics program, so don't be expecting that.
