You can find a lot of different loads on the internet. But I always like to check "net" loads against an actual published authority. Sometimes a forum writer will accidentally keystroke an incorrect number or forget to put a decimal point in, ect...ect.
So, for a "cheap" yet very useful reference source, you can buy an "USA Loadbook"
http://www.midwayusa.com/eproductpage.exe/productview?saleitemid=575915&t=11082005 for the 22-250. This one is on Midway, but all of the on-line shooting supply stores have 'em. These simply reproduce all of the 22-250 loads from the various loadbooks such as Hornady, Speer, Sierria, Nosler and such. They don't have all of the "other reloading goodies" that you will find in a full blown reloading manual.
But for the price, it does give you something to check a load against to make sure your not going to over charge or under charge a load.
