I've got a older model Savage Model 16 I bought use in 300 wsm. Stainless steel and threaded barrel. Blind box mag and no accutrigger. Bolt doesn't stick but pulls bullet back to ramp and won't kick bullet out unless super fast and lots of force. No ball or hole for one that I can see in the bolt. Just copper colored groove on inside of bolt. Any suggestions. Love the rifle and it's a real tack driver.
