I acquired a 'shooter grade' 99c in 308 a while ago, I bought it as another donor to bore up to 358. When I got the rifle, I put a one down the pipe just to make sure it goes boom before sending it off for rebore. I'm sure this had nothing to do with reboring, the safety functions like normal, the only issue is when firing the gun the safey 'sort of' engages back on. The tang lever slides maybe 1/16" of an inch or so rearward on firing. When the trigger is pulled for the next round, there is a partial click but not firing pin drop. If you slide the safety fully forward again, like that 1/16" or so, it fires again normally. You can engage and disengage the safety like normal, only on firing does the safey slide a bit rearward and prevent the next round from going boom.
I haven't pulled it apart yet to peek at it. Anything I should be looking for? It's been a couple years since I've had a 99 fully apart. Is there a detent for the safety slide?
Yes, after a rebore when I went to test fire it before scope mounting. Bought the gun used, checked it over when I got it that the action cycled ammo correctly, the safety positions worked in safe and fire modes as intended, and then at the range just put one down the pipe to make sure it fired correctly. That all worked fine. Sent it off for rebore.
I highly doubt the rebore job had anything to do with the safety, I didn't fire it enough before hand to realize there was a potential issue. I'm not really that worried it, just thought I'd get a head start with asking here first on what to keep an eye open for before taking it apart for examination.
I tweaked the spring shape to more closely match the diagram. After reassembly the 'position positivity' seems noticeably better. I'll have to get back to the range after new year's to have another testing session.
