recently I purchased a new scope and have been messing around with this site.
http://www.nikonhunting.com/spoton/ now for those that dont have one of the nikon bdc scopes it is still useful. there is ballistic tables for all the major brands of ammo. now I dont know how good/accurate they are but for those out there that would like to know some of the info on their loads they buy it might come in handy.
