Nah, Redhook, I wouldn't worry about it. If you're loading for max accuracy, you could segregate these out as plinkers, if the crease doesn't disappear when resizing.
I've had tired brass split, slightly, when seating bullets--really tired brass. I just go on and shoot them and then throw the case away.
That's the good thing about low-pressure loads. You can get away with stuff you wouldn't begin to try with a rifle or a .357.
