Buy Loadbase by Patagonia Ballistics here at the LRH Gear Shop. Through a specail agreement with Gus we are the only source of the individual "Desktop" or "Mobile" Editions of Loadbase. And of course you can buy the combined Edition, too. LoadBase is one of the most popular and probably THE most robust of the ballistics software programs used by the more serious LRH crowd. Its developer, Gus Ruiz, is a long time LRH member having written a key article on ballistic software for the site.
