Yesterday I shot it at the range. Actually I carried an arsenal to the range and shot them all, P08 Luger, KelTec P3AT, Nagant revolver, Remington Mod 1100 SA 12 ga, and my recently completed AK-47 Super.
But as Mrerick suggested, the TulAmmo steel cased ammu was not fully functional and the Federal was flawless.
The Tulammo apparently has a lighter charge, or a smaller bullet, because it would appear that the chamber pressure was lower than the Federal. The reason I say this is that while the Tulammo cycled properly, after the last round it did not lock back. The Federal locked back after the last round every time. I assume that this means the bolt is not cycling all the way back, but is cycling enough to pick up the next round from the magazine.
If this is the case, then I would imagine that over a period of time there would be other problems, like a light load not cycling back enough to pick up the next round.
But the Federal worked every time.
The Super AK was flawless in operation. Its a Romanian AK with a Yugo RPK machine gun barrel grafted on instead of the standard AK barrel. This makes it about 6" longer.
