Not too sure what they mean by "Interactive" since it still does what it always did. The only significant change I am aware of is that they changed the ballistics calculator from one that was easy to use to one that isn't as easy to use but is supposedly marginally more accurate if you can supply all the data it requires. Might as well just load up a box of shells and start backing away from a target now.
Mmmm if it was free I would be all over it.. you can find that data on the web regardless and if you wanna get real specific get on a caliber/gun specific forum and ask in the reloading sections for FREE.
Actually, I sort of object to even mentioning it on here. If it was free - or if the data was unique - then I'd be all for it. As it stands, they want you to pay for data that is already available elsewhere on the internet. Posting a link to it is really just helping them advertise - without contributing to TGT.
