Did a quick search and didn't see this posted. Ruger has a safety bulletin out on its Precision Rifle. For those with the aluminum bolt shroud, there can be an interference with the firing mechanism. In rare circumstances, push trigger, click, round fires when bolt is lifted. Typically involves light primer strikes too. Ruger will send a replacement shroud (no charge) if your rifle is in the specified serial number range. Here's the link.
