I just got my first case of 357 sig ammo - Federal AE 125 FMJ - and the very first round I looked at had severe setback, over 1/10 inch (obvious on visual inspection without comparing to other rounds). Is this something common for 357 Sig? The rest of the rounds I looked at were OK. I've seldom seen a factory round with problems (the ones I saw were usually Russian made) in 9mm, .40, or 45 - probably less than 5 in the last 100, 000 - so seeing this on the very first makes me wonder. Not uncommon? Fluke? Bad omen? Waiting for the gun to arrive, so I can try them.
