I've wanted one of these big bastards since I first saw them. I finally got it the other day. Took it out today, only had time for two quick mags through it, and all I had was Winchester White Box 230 grain FMJ. First mag had about 10 assorted failures. Stovepipe, FTF, and FTE. The second mag, (different magazine) only had one FTE. It was the next to last. Both mags were loaded to full capacity at 15 rounds. This is a brand new gun. I know these have a spectacular reputation for reliability, but does anyone else have any issues with any particular ammo out of theirs? I'm gonna get some other brand ammo and test them when I have a spare moment.
