that's all i buy for my g19 is the federal champion, since it came to walmart, and WWB jumped in price. great range stuff. champion 9mm is $9.47 in my area, whereas WWB is close to $13. both good ammo, i just prefer the cheapest quality ammo i can find for the range.
actually found 1 box of champion .45 at walmart yesterday. first time in at least a year.
I checked WalMart today and they had Winchester white box 100 rds for 23.47 I had just bought 10 boxes of the Academy/Monarch (Barnaul Brown Bear) for 7.99/50 two days ago. I'll check next week to see if they still have it. Academy also sells the Brass Cased 9mm for 11.99. It shoots well.
