All of a sudden I'm getting ad's from bog box stores and even Midway selling Winchester Military Grade 2 3/4" #00 Buckshot. It's $4 - $5.50 box of 5 so it's priced pretty descent. It's OD green with some type of anti corrosion black coated brass. A Midway review says it's black anodized. Does anyone know what, if anything makes it different? Midway reviews are pretty good.
