here is a pic of some of the fed prem rounds that had issues
notice they all have a 70 degree mark on them, I am guessing that is from the bolt as it rotates and the shells dont. Its like they are jammed solid into the chamber after being shot.
Have you had a look at your bolt face? Hopefully you didn't get any flame cutting on it from the pierced primers. Definitey stop shooting that gun.

Incredible story for a new rifle and factory ammo. You may have a short throat, allowing those particuar Federal bullets to engage rifling hard on chambering. This would cause a significant rise in CUP, and if your firing pins a little long and sharp, a pierced primer is easy.
You said they fell out of the cases on extraction. Was the primer pockets enlarged this much as to allow the pierced primer to be pulled from the case on extraction? If your primer pockets are enlarged as to allow flattened primers to fall out, there is some serious chamber pressure going on here. Probably in excess of 100,000psi! Case head stretching of 0ne thou, is considered excessive pressure. Do you have calipers to measure the fired cases just forward of the extractor groove and compare to same place on a new Federal round.
Please let us know the outcome.

Go No Go Guage results
I ordered some head space guages from Pacific Tool and Guage. My gun has way too much headspace, I can insert the NO GO Guage and close the bolt with zero effort. It so loose that I can get it to fit with a 4 thou feeler blade stuck to the back of it.

I also got an email from Federal, stating they have seen the pimer issue in savage 270 wsm rifles. Apparantly they have a slightly smaller throat than other rifles, causing high pressures and case distortion. Federal stated that they couldnt ship the ammo for verification (canada/us issue) So they where sending me a cheque for what I paid for the 3 boxes of ammo.
The bolt face looks ok, and the chamber looks perfect. I am ordering a barrel nut wrench and making a barrel vise. I will set the headspace myself and post the results for y'all.

I'm following this with interest in case I ever want to rebarrel mine. I'm curious how tight that barrel nut is.
Good luck!

I do NOT like the look of those spent cartridges!
From the small pic it looks like cratering, flattened primer, and pocket expansion, all in one neat little package just waiting to go boom...
Sorry about your rifle, get it checked.

I don't want to try to scare you or to make you a moral and i don't know your reasons for not bringing it to a gunsmith at first, but a loose primer is always a sign of pressure surge (or very soft case head) and should not be taken like a funny thing, as your face and your hands are standing in front of at least 65 000 PSI. When this occurs, you have to question yourself about using the gun again, as this situation can lead to a case head seperation which can wreck the action (and yourself).
Trying to fix a headspace issue without fully knowing what you're doing, even if you get Internet infos from "experts" is not a good idea neither.

ill buy it cheap
And couple of years ago I was shooting a brand new Savage 7 08, 3rd shot of Federal the extractor came apart and the brass jammed, Rifle and ammo went out for warranty Federal and Savage each blamed the other have not felt good about either company since. Still have the rifle and have never had another problem but I don't use Federal ammo in it.
I had a savage 111f in .270 wsm years ago with the exact same issue. With handloads it showed sticky bolt lift and shiny spots on the case heads with minimum loads. Same thing with a variety of factory ammo.
I ended up rebarelling it.
Never did figure out the exact cause - I also bought it secondhand, and the gunsmith I took it to didn't inspire my confidence and tried to tell me it was because the .270 wsm was badly designed - so I didn't leave it with him.
