I have used Google to search and have not come up with a clear cut place to buy components, such as primers. There are a lot of mil surp ammo, and I think Hornady is the only sporting bullet maker, but it appears that is all.Is RCBS the only die maker?

CH4D custom die makers has .50 BMG dies
CH4D Custom Die Co.
For practice projectiles, brass and powder try Jeff Bartlett @
Jeff Bartlett Reloaders
and Watsons Weapons
For primers try
Widener's Reloading
Outdoor Guides Impact Guns

As far as sporting bullets, I take it that you mean for hunting. Any .510 caliber bullet such as those for the 500 Jeffrey and Nitro Express will work. You can find these almost anywhere, such as Midway USA

Bubba,
JS_280 has already listed great places to get you started.

For 'in depth' discussions on BMG related products/issues go to http://www.biggerhammer.net/barrett/wwwboard/ and use the 'search' option. Also look in the archives at http://www.biggerhammer.net/barrett/wwwboard/barrettarchive.cgi for ton's more BMG info.

Thanks very much for the information on the .50. It is hell to have a rifle and no ammo.
