And I think the problem with the 17 HMR was related to the fact that they probably primed them prior to putting the shoulder and the neck in.

smaller diameter so it's just easier to get the blob of uh primer material down into the case with the with the prior to putting the neck in and then once you spin the primer into the rim you don't want to do any more stress relieving because that'd be a silly thing to do so they didn't they didn't do it and and early at least early samples

of 17 HMR suffered from varying degrees of stress corrosion cracking shoulder.

And you see a longitudinal split like that,

What's caused it is stress corrosion.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Yeah, so for a lube dent to cause that, it would have to be kind of fatigue related.

And so if you've got lots of firings on them and you bump the

you bump the hardness up and you haven't annealed, then you have the potential, obviously, to cause that.

But my experience is that they're almost always...

caused by stress corrosion cracking.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

No, no, I'm not suggesting that.

Firearms Radio Network (All Shows)

I'm suggesting that when they see that it's caused by stress corrosion cracking, my experience is this rarely, unless the leak progresses to the point where the leak path extends aft out of the gun, you know, towards the bolt,

Firearms Radio Network (All Shows)

There's no problem.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

There's no harm to the firearm.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Just throw the case away.

Reloading Podcast 565 โ€“ Jeff from Bulletology

And if you're starting to see it on reloads, you might think about annealing the case, okay?

So for these...

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Does it increase susceptibility to corrosion?

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

The answer is no, quite the opposite.

Is the case more corroded during the annealing process?
