I have used CCI 400 in Peterson SRP 260AI brass with no issues as well with 47.5 gr. of H-4831 and 140 gr. bullet.
Took my test loads to the range today and am pleased to report that everything went well.There was some minor cratering but no more than the winchester primers displayed,rifle is a savage.Worked loads back up to my normal load of 26.0 grains of benchmark and 50 grn v-max 26.5 is book max.Next will come accuracy testing.Thanks to everyone for the replies and info.

Disassemble you bolt and make sure you don't have the tiny metal discs from pierced primer inside the bolt head.

Archemedes action, 6.5x47 lapua, 130g @ 2800+ , CCI 400 for over 2 years, 1500 plus rounds , not a single problem.
Accurate load for me.

I have been using 400's for more years than I want to admit too, and as of yet haven't pierced one.
As far as the savage firing pin they all make the primer look cratered. I've been shooting Savages since the early 70's and the primers are always cratered, maybe they just don't round them off when they make them. Even on the few I have had bushed they still look somewhat cratered.

Did that, didn't find anything. Cleaned it all anyways before reassembly.
You will be fine since you're like me and see no reason for a screaming hot load especially to shoot paper with on a nice day.... Expect the CCI small rifle primers to flatten at even medium power loads... That being said I use them for all my .223/5.56 rounds and just expect it to happen.... Although I have never had it happen to me I keep the gun pointed down range when chambering a round in the AR platform in case of slam fire... That advice is good for any primer in a free floating firing pin system though.... If you don't have one yet I HIGHLY recommend a chronograph.... I have used the pro crono from competition electronics.... Used their stuff in 1/10 scale electric car racing for years and like their company.... I have tested everything from arrows to pellets and from pistol to shotgun over it...
To be honest when it comes to pistol and rifle I change primers without reducing the load at all but will still check with a crono and look for anything crazy on the brass etc... Now shotgun that's the one you better know exactly what you are doing by changing ANYTHING especially primers.... As a matter of fact changing anything other than what's in a book is not recommended.... With the covid crunch unfortunately we have had to do some changing of components that I would have probably never done and because of it learned a few things about it.... Fortunately all good.... But it's a dangerous experiment with shotgun and I don't recommend it unless you know what's going on in that hull....

With an excellent firing pin/boltface you can get away with a lot.

I had a problem with ftf, and solved with a PTG bolthead which has a smaller diameter firing pin hole plus a new spring which frequently becomes weak on a Savage. In addition the protrusion often needs adjustment as well. Not uncommon for a Savage.
I put in a PTG bolt head in my savage and it helped immensely with cratering.

Please remove my cell from the internet thanks.
Done and my apologies Ben.
Hope you are recovering well.

Thanks, I was getting a lot of spam calls. Spent this week in the hospital. Not enough blood in me apparently.
I believe this has been going on for a while as I talked to you last fall about bushing some Savage bolt heads and then heard that you got sick. But once again take care and get well! I can wait.
