Thinking head space issues, ideas?

[Winfwt338-06]

Primers back out of factory or reload ammo in my 1907 Savage 99 TD 38-55. 26" round barrel. Have fired very few rounds since seeing primer issues, they aren't flat, just back out of case. Would love to shoot more, but want it safe. Thoughts, ideas welcome. Thanks in advance, Scott.

In my experience it's been under pressure. I've read it's common in rear locking actions, especially win model 94. In my case it was a high wall 38-55, finally figured it out when I noticed the bullet crimp wasn't being opened all the way on a fired case as well as the primer backing out. Bumped up the load and it went away. But the fact this happens to you with factory ammo has me scratching my head. Maybe headspace?

This is totally normal.
Nearly all loads under 40,000psi will back out primers, there isn't enough pressure to push the case back hard enough to push the primer back in.
Hope this helps.

Cheers.

It is a combination of lower pressure, allowing the case to grip the chamber before it moves back pushing the primer out/back of the case the amount of the head space. If the head space is within the SAMME specs, it should be ok.

Try resizing with less shoulder bump and see if the primer still pops out

38-55 is a straight walled rim cartridge.

Thanks for the replies. Will try bumping load up, will keep y you posted

Sounds like a crimp needs to hold that bullet longer to promote more pressure to make it all work correctly....

Do you think this holds true with modern factory loads also?

Not a straight walled shooter...but aren't most all straight wall factory crimped...even .22lr are straight wall and everyone I have pulled apart are crimped...

Yes, they are crimped. Maybe sporter low pressure to a counter for antique weaker actions.

It is easy to see if there is set-back on a Sav 99 as the the locking abutment is where the rear of the bolt meets the receiver when the bolt is closed. Just open the action and that area is exposed for inspection. I have seen several 99s with set-back because of hot rod reloads. The .38-55 uses the same head space gauges as the .30/30. A "FIELD" gauge would be cheap insurance, as I'd say a Sav 99 TD chambered in .38-55 has some 'collector' value.

Thanks, will take to my gunsmith and have that checked

How is the barrel to receiver connection on that TD? Worn or good and tight?
