I had quit using them recently anyway. Was having a lot of light primer strikes. I assumed it was my gun and changed everything related to making it go bang and still had issues (no problems with other ammo). Here is the kicker, it only happened when it was below about 40 degrees. Really weird. Still thought it was my gun, have since talked to 3 other people at matches who were having the same issues. Switched to American Eagle 147 for match use and have not had one issue since.
