I looked back, and found a similar 9mm thread about it, and saw some confusing answers and arguments at the end of it.

I bought a case of Independence 40 SW 185 gr fmj, some time back.. I'm unsure if that brand is factory 1 time reloads or not, but the primers are not brass colored. I'm new to this stuff, and still trying to learn...anyways... I fire these rounds out of a G22, and to me it looks like the cases expanded so much, that it would stick in the die if you tried to resize it.

Why are these cases expanding that much in a barrel that the round is supposed to be designed for?

Thank you for your time.
