Has anyone shot the Federal 223 55gr FMJ 100 round Value Pack at Wal-mart? I just picked up 400 / 4 boxes of 100 rnds for $37 a box thought I would try it. The store only had 7 boxes so I bought 1/2 of it. They just got a huge shipment of Federal 50gr HP's 200 rnd count for $75 a box about 76 boxes. The sporting goods store manager said it would all be gone by Saturday. I'm thinking of going back and purchasing the last 3 boxes of 55 gr and a box of 50 gr. My wife was in a hurry to get home and pick up the kids from school or I probably would have bought it all.
