A firearm reference database will never be “out of date”. The guns don’t go away, nor do the thousands of existing models change. So as a reference for existing models, this database will stay relevant.

The only thing it doesn’t capture is the new models that are released two or three times per year. That’s a gap, to be sure, but the data on the file is never obsolete.

So, for example, if I were writing a novel and wanted to include some data about a .50BMG “sniper rifle”, I could turn to any of the 67 models listed in the current database for some great and detailed information… right down to the velocity and trajectory of a specific bullet at 1000 meters. Sure, maybe next year Bushmaster will release a new model that isn’t covered in the data set. It’d be nice to have that update, but it certainly doesn’t invalidate the information already on the disc.
