I have a Model 12 LRP in 6.5CM that only has about 100 rounds through it. Took it to the range today to get more practice with it. I was shooting Hornady's 129gr SSTs. After about 15 rounds, I would get a click from the trigger but no firing. I would cycle the bolt halfway back then send it home and it would fire after about 4 times it would not work anymore. It would not show any marks on primers. Probably very simple, but what do I need to look at first? I reckon with all the knowledgeable Savage shooters on this site, somebody would know where to send a newb like me to look. Any help greatly appreciated.
