Just recently began reloading. Stocked up on rem 7 1/2 SRP for the 223 savage.
Have about 400 fired so far and began having dud primers recently. Like 5 out of 25 rounds for load develpment with staball match this wknd.
anyone else have this issue with these?
 
They are probably the most robust SR priner out their both in terms of brisance and cup hardness. I have several pistols and a lever action rifle that hates them. They often won't go off no matter how many times they are struck. If i put them in any AR or similar gun they work 100%, even the "duds".

Pull your bolt apart and check for oil or some crud in there . I woukd also check and make sure your primers are seared properly , you shoukd be able to feel the primer seated just deeper than the case head.

Try them in a different calibre or rifle with a known good firing pin spring, maybe the savage has a weaker spring or the firing pin channel has old oil and crud in it.

Many shooters last weekend had FTF issues in the cold weather, I know all of these shooters and none have any problems in -10c .
Savage firing pin springs are well known for short life ( two or three years) .

I had similar issues with a pretty high end rifle this past year.
Turned out it was my firing pin walking itself out of the cocking piece.
After turning it back in, a wee bit of blue loctite on the set screw threads has solved it for now.
 
Are they new stock, or second hand? I see a lot of very old primers for sale on the second hand market, and you never know how old they are and how they've been stored.
 
these are all newly purchased primers.

Decided to dis assemble the bolt to see what the condition is and omg. There was 10yrs worth of grease and sludge all up inside the bolt body.
Cleaned it all out, lightly oiled it and reassembled. Will take out next wk and see if that was the cause of cold weather primer issues.

I think you found the problem!

Since you're using Staball, a ball powder, and you're shooting in sub-zero temperatures, You need a magnum primer for reliable ignition. There's nothing wrong with primers or the gun. Putting a hard crimp on the bullet will help with ignition but magnum primers are the way to go. Ball powders are harder to ignite than stick powders especially under cold conditions.

Well, got out to range again.
-14, no wind.
60 rounds with same primers, no problems with dud/misfires

Lesson learned.
Clean out any built up grease within the bolt body/spring if shooting in winter.

Definitely a requirement on any new rifle, packing oil is not very luby and great for collecting crap.
Savage bolts are not too bad at least to take apart and reassemble. Still blows my mind how many goddamn parts they use in a bolt assembly, an entire Glock pistol is like 37 parts, Savage bolt isn't far behind that lol

Standard Rem primers are hotter then most other magnum primers...they flash hard.
