Just from a quick survey of Midway USA, Scheels and Sportsman's Warehouse. For cheap deer loads, .243, 6.5 CM, and .308 all run about the same price. Sometimes 7mm-08 is also that same price, sometimes it's a bit more. .270 and .30-06 are usually a few bucks more, everything else and anything with the word "Magnum" in the name is pricier.
