No problems here locally, but Cheaper Than Dirt bulk 5.56 NATO stuff is about wiped out. I did just pick up 300 rds of .45 ACP Federal 185 gr. JHP stuff for a very reasonable price... 131 bucks shipped. .45 ACP is not as popular as it once was, thank Goodness for that.
Just checked, they have plenty of 40 S&W bulk ammo...
