I have about 30 years experience handloading but all have been bottle neck rifle cases. I can consider myself lucky as I never had a primer sunk to deep in the primer pocket. Now loading for my 500 mag using starline brass and CCI Large rifle magnum primers. The last batch had 5-6 out of 25 with low primers causing light strikes and no detonation. My question is can I do anything to save the brass? I know it’s only a few pieces so if not it’s not the end of the world. Typically I would pound bullet free dump powder then fire off the primer making it safe to start over. Can’t do that with these. Suggestions?
Primer seated to low in primer pocket.

- Start date
That's what I'm wondering.
And I'm wondering if he's seating by feel, which could easily lead to this issue with deep primer pockets and short primers???
I have no empty brass tp
Measure yet. You should be able to see the difference in the two. The one primer is definitely seated deeper. Now if that’s due to a short primer or a deep pocket I do not know yet. Either way no go boom so I am either gonna drop them in the tube at the range or figure out a way to get 5 live primers out without losing my eyebrows

Is the large rifle magnum primer the correct one to use? Some of them have very hard cups.
I've removed a lot of primers from cases without incident and afterwards have reused the very same primers. I'm just very gentle when pushing them out with my Lee Decapping Die (and just in case, I do wear eye protection).
For example, Sig's 277 Fury Hybrid cases I bought verily recent all came primed. In order to neck them up and size them I had to removed the primers (150 of them). After processing them to a .308 dimension, I primed them with the primers I had removed, loaded them up and fire formed the cases. The primers and cartridges worked great and I was even surprised by the really good SD's I got. I've even done this to some extent with other brass, including some of my Lapua cartridges.
Just be gentle and you can reuse the primers.. . . or not.

To answer your question yes I am using a rcbs hand primer going by feel. Safe for me to guess theres a better way for this case?
I made two or three attempts in both single and double action

Pull, dump, carefully(slow stroke) deprime. Load up case with a load that calls for a large pistol primer and see if fires. That will answer all the questions.
new cases will have an "R" after the "Mag" on head stamp to signify rifle pocket.

Hodgdon Powder has generated load data which recommends using Winchester large rifle primers.
Interesting info, but i dont see it fixing defective primers?
Hey so the s&w 500's are notorious for being shipped with screw on mainspring being set to loose/low....do a google search
Any way fully tighten mainspring screw usually fixes this.anyways don't fully remember details cause it wasn't my problem.
Just throwing this out there
I don't have your pistol in hand to diagnose but have seen this firsthand...
Yeah I just went back and did a Google search from my buddies problem.
There's tons of threads on Internet for these pistols with light primer strikes and screw on mainspring needs tightened.
Also don't think there is no such thing as primer seated to deep.to short is a problem not to deep.no such thing

Yeah, I’ve never had a primer seated too deep, had them not deep enough with fail to fires though. (Hand held seater) Fixed those by pulling the bullet and powder and seating the primer with my Lyman ram prime die.

Yes, YouTube has several different models with light primer strikes (especially shooting double action). Remove the grips, turn the strain screw in. Test fire.
I agree, Primers need to be seated until the anvil rests on the bottom of the pocket. I know a few guys also crushing .007"
