I have shot .357 SIG (lots), 7.62x54 russian, .38 spl, .357 mag, 9mm Makarov, and .45 ACP. All of it has been perfectly serviceable, accurate ammo. The 357 SIG was not particularly clean burning, and I did get a few hard primers (very few).
Someone above mentioned reloading problems. I have not had any problems reloading large quantities of S&B handgun brass. I never have tried reloading their rifle brass so I can't comment on that.
Overall, S&B is my favorite "economy" ammo. I prefer it to any other low-$ ammo including Federal American Eagle, Winchester White Box, Wolf, and UMC.
