I can only say for the 30-06 really as it's all I've bought. I take that back I bought a friend a box of .243 as they were sold out in the town he lives. I live almost 3 hours away and they had some here so I picked up a box. I think it was $18 at Wal Mart for 20 rounds of Winchester Super X Power Points.

Anyway, for the 30-06 when Wal Mart has it in stock which is rare the Federal Power Shok stuff in both 150 and 180 grain is $14 a box. This same stuff seems to range from $18-23 at other places. $18 being about the cheapest I've seen it elsewhere. The Winchester is $18 and I'm not sure on the Remingtons. The Federal Fusions I shoot are often around $30 a box at Dicks and other places here however, sometimes you can find them on sale at Dicks for cheaper.
