There seemed to be some problems with it over at the HS2000 board for awhile, FTEs w/9mm. They also had some problems with other brands.
I have shot a bit of it in 9mm, .40S&W, .38spl and .357mag. Have had no problems to date. Autoloaders are both Rugers.
Went to the range with a couple friends about a month ago. They had problems with the USA .40S&W. They were shooting it in a Sig, Glock, Ruger and an HK. I let them shoot some S&B I had with and they experienced no problems with it. Since, I have put three or four boxes of the Winchester USA through my Ruger with no problems. Just fired a box through a Glock 23, no problems.
My perception is that they may be having sporadic quality problems, at least with the .40S&W. It may be that specific lot numbers or a specific manufacturing location may be involved - no facts at hand. The folks at the HS2000 board will probably say the same with the 9mm that they seem to be having problems with.
