I was shooting a primer test for my son’s 223 savage bolt action and got a pierced primer on the 3rd CCI 400.

Also seeing a lot of primer flow into the firing pin hole

That ended the test and range session. Trigger is not functioning. Got the gun apart now trying to figure out what’s wrong. Maybe a piece of primer inside the bolt or it busted the trigger?
 
Try a different primer, thicker cup. Reduce load. Buy a cartridge that will produce the velocity you want at midrange load pressures.:) 22-250 1-8" Twist.. 22 Nosler.
The missing primer metal is probably in with the firing pin. 20190728_072239.jpg

I would consider disassembling the bolt and make sure everything was right in there. The Accutrigger is a pretty solid design, I'm not sure how a piece of primer would get back that far. Please let us know what you find.
 
I've had that problem on my LR-6.5 CM I built till I went to the HP Bolt. I found out that mfg are going max clearance on all the bolts, 0.003"-0.004". Which is about double what is required. Too much clearance and it will happen all the time even with heavier cap primers like Rem 7 1/2 and CCI #41.

You may find that the primer FP cap in the bolt, FP hole. Only thing to do is tear it down and clean it. Hopefully that is all it is and it did not damage the trigger group.

Note, I was in the process of testing different primers as part of load development when this occurred.

My son shoots this rifle in F/TR, limited to .223 or .308

Checking my log book we have 470 round on this barrel with this load, shot during the heat and cold, but I was using 205M primers. They my be a little thicker than the CCI400.
 
Primer flow as shown in photos is typical of weak firing pin spring. Usually accompanied by occasional "biscuit cutting" as also shown. Savage rifles have a well earned reputation for poor springs, a progressive condition that manifests itself and gets worse with time and use. Which is why the standard tuning up with new Savages includes replacing the springs. It's a simple fix.

Excellent idea. On the search for a spring upgrade. Worth trying before sending bolt off to be bushed
 
What exactly is meant by "Having the bolt bushed," reducing the size of the FP hole? Oh, and who does this service, Savage, or gunsmith? Standing by for your "spring replacement"....I have two Savage rifles ( .223 with a few hundred, .308 still unfired. Both rifles FV12)

Thanks for clarity and schooling,

Seems like I remember reading on the Savage Shooter forum about this happening with Savage rifles. The thread I was reading "fixed" the problem by replacing the bolt head with one from Pacific Tool and die.

If this is accurate, perhaps this could fix problem on the Savage? Might be a little cheaper and quicker turnaround than re bushing the pin hole?

PS: Well, reading More on the Pacific Tool site, it may require fitment to receiver by gunsmith, and does have 8 weeks lead time.

Oh well, I will just be still and sit over here.
