Federal American Eagle 125gr FMJ and Remington 125gr FMJ.
I hadn't yet tried the American Eagle, and I was interested to see how the inexpensive (relatively, at least) target ammo from the company that invented .357 SIG fared.
Quite well, as it turned out. There was only one jarring note to the range trip, and it came from the Remington stuff...
That makes 568 total rounds fired with three failures to go completely into battery (#63, #78, #126) and three failures to feed (#221, #224, #282). 1,432 rounds left to go.
