It wasn't meant to remain reliable, and nothing about this is intended to be profound-just plain info. I'm familiar with the fact that almost no handgun will always have a perfect operation, even a quality 9mm. My 100% German, a nice Sig P228 (1994) had its first malfunction today, a stovepipe jam, after about 1,000 perfect rds. using mostly Federal Blazer. This ammo was in the car for at least two Months. No emotion here, just boring info. The .22 ammo--two mags x 12 rds. each--would not even ignite in the new "S&W M&P" .22. The brand is Federal Champion (blue box), but the ammo was only in the car about two-three weeks, because I bought the gun around Dec. 15th. This Federal .22 ammo easily could have come from an older batch bought a few years ago, which had been stored in an air-cond. room.
