Oops misconstrue. I've noticed leakage in some but, not all rounds. About drying out and becoming useless, that was a rumor I've been passed.

As for the OP, I've not had any problems with rounds in my Tiberius. Then again, I'm not using an adjustable bore system, and my gun is a blow forward.

That being said, what sizes were your inserts? I ask because the casting seams are super thin and should shear off when placed against any significant load.

Depending on who's philosophy your following, you should be between .687 and .690 (which is my recommendation).

The casting flaws I see are typically fringes on the skirt trailing edge (sticking up between the fins) and the injection point on the nose (often differently sized and not perfectly centered) I've got no evidence of it negatively affecting flight though.
