To start, I don't know if this is a common problem with rimfire ammunition, or my gun specifically. When shooting, I'm getting (usually) 2 misfires for every mag. Not back-to-back, or even the same number in the mag (every 3rd round, or every 5th round.... for example). I've looked at the rounds that misfire, and the shells that fire fine. Same mark from the firing pin. Sometimes the misfired rounds fire fine when loaded back in. Sometimes they don't. It's a Savage B17F left hand shooting Hornady 17 gr VMAX.

Thoughts?
