The best advice as far as components are concerned is that some simply work better with your specific gun than others. I ran into that situation about 6 months ago. Got some once fired 22-250 brass, but the resizing die I was using would not resize the cases enough to fit the chamber that the rounds were intended for. Got another one, problem solved.
Every once in a while, you may run into things like that, but that's the only issue I've had so far.
