Hey Eddie,
Check out Midway USA, they have good deals on most ammo, they also have reloading stuff. I load my own, exclusively, so I can control accuracy. I use a mil-dot recticle, once one is familiar with these, a range finder isn't necessary. That .303 might knock your shoulder off though, mine is the carbine version issued to paratroopers, it kicks like a mule.
Oh, the board is coming around, a little faster than I expected.
Take care!!!
Andy
