Gander Mtn sells Winchester White box .30-06 with 147 gr FMJ. I believe it goes for $11.97. A buddy of mine uses these for target practice in his Savage 111 and does well with them. Some local Wal Marts have been selling Federal Power Shoks (Blue box) for $9.97. Dunhams usually sells Olympic (Greece) and Hot Shot (From Bosnia, distributed by Century Arms). Both have brass cases, boxer primer's and are in the $10-$12 range.
The Federal shoots best in all my '06's. I've not had much luck with the Hot Shot ammo. Olympic shoots well in my bolt actions, but not the single shots.
