You have come to the right place. It' s great to see some new guys on the board! Anyway, a Remington 700 is a fantastic gun, especially the BDL. For deer, and cheap ammo, the .243, .257 Roberts, .260, .270, .280, 7mm-08, .308, and 30-06 all offer lower ammo prices, and all have taken alot of deer. I believe all of those calibers can be found in the Remington. Magnums will work fine, but with higher ammo prices than you might be looking for. Other than that, welcome aboard, check out all the other forums for more information.
