116 Random light primer strikes- help???

[hafejd30]

116 in 30-06

Winchester case
Cci 200 primer

Right casing- shot one round prior to one on left
Left casing- happened on 3 rounds out of 27. First 2 I re-chambered and went off. The other would not fire.

Next round would fire same as the one on right

Any idea what would cause this? Gun is new (few years old- won at banquet and not fired until now) Rcbs hand priming tool is used on countless other rifles and casings without issue.


Image appears as there is flow around firing pin- not the case just appears that way in the pic

First thing I would do is disassemble bolt & clean, may be dried oil or something in bolt. Second I would check brass to see if shoulder is set back to far.

Bolt was disassembled and cleaned After the first misfire. Brass is neck sized only. I did some research and will switch to Winchester primers and see what that does. Thinking maybe the firing pin spring isn't hitting the harder cup of the cci primer Enough to set it off

Anything new?
I had two FTF, but I didn't pay attention and just put them back in, and shot them.

Used the Winchester primers, shot one went good. Shot two blew a hole between the primer cup and the casing. This was a friends rifle. He since got rid of the rifle and I built him a custom 260. If you want things done right you do it yourself. Problem solved lol

I bought a used 116 about 3 years ago. It was fine for about a box then started misfiring. I streched the firing pin spring about 1/2" and the problem went away. I figure that the prior owner put his weapons away with the firing pin cocked. I put a new spring (2lbs. heavier?) that I got from Wolfe, and haven't had a misfire since (at least 200 rounds). Hope this helps. By the way, I lube my bolt internally with graphite. Cold doesn't seem to affect it in any way. Paul
