I also shot CCI standard, Winchester Super X, CCI Mini-Mag, and Federal Bulk. None of them had a single problem. I shot about 100 rounds of each, except for the Federal. I think that brings my grand total of Federal bulk to about 1100 rounds without issue.

I guess the Tactical AR does OK, but I'll take flawless operation over 3% failure any day.

Unfortunately I shot from my bipod again yesterday and I wasn't consistent enough to determine whether one type of ammo was significantly more accurate from 50 yards than another. Everything seemed to have pretty similar groups, so I guess that's a good sign.

I think I'll stick with Federal for my cheap plinking and plan to do some more careful experimentation with others to pick a premium round to use. The unopened box of Tactical AR is going to be returned.
