Reloading question

[armalitesheepdog]

Would this be considered a flattend primer? Sign of over pressure?

 

[Creedmoor]

The primer wouldn't bother me but those extractor/ejector imprints just might.
What pistol were these shot out of?
Whats the load and bullet please?

 

[R3p1lc3]

I'm no expert doesn't look extreme. Using federal primers?

Agree those extractor gouges look excessive

 

[Aszerigan]

Primers are fine. Brass is beaten though. Is there something on your breach face?

Seems clean

I dunno, brother. I load Treefiddyseb'n pretty hot (158's at 1,500+ out of a 6" tube)...

...and those primers up there still look like dogsh** compared to anything I load.

Look at the lack of remaining radius, and migration. And these are thin-wall pistol primers; they don't tolerate nearly as much as do rifle, when compression transitions to shear at that radius as it is pounded out to 90 degrees (or worse) by overpressure loads.


@armalitesheepdog, punch a few out, and look at them sideways. They look like a mushroom, don't they?



Tilt the can less.

I will have a look

Jest ponder it: that pistol was originally designed for a 20,000 PSI bang. The bangs you are putting through it--if appearance says anything--are probably over 40,000 PSI.

Ruger doesn't know how to build anything WITHOUT overbuilding, but that doesn't mean your slide won't end up in pieces in your hands and face, when you blow a case.

What's a 1911 rated for on breech-face thrust?




...bet it ain't 40k.

 

[Waldog]

The second case looks like it was shot out of a first or second generation Glock. Early Glocks left a small rectangular mark on the primer . Hard to tell from the picture.

This guy reads my mind.
I am a little concerned about the primer flow into the firing pin channel.

Disclaimer; I haven't ever loaded 10mm, but have some experience abusing a Ruger Security Six. (lots of 2400 and 125gr jacketed hollow points)

I really don't know,
I understand what you are saying, but the primers just dont bother me. The 10mm has a good web in the bottom of the case. It can be a hot cartridge if one wants it to be.
I only have two 10mm's A Delta and a HK, I really dont shoot either anymore. I cracked the frame of the Colt and it was replaced under warranty with the beefed up model and with the HK, parts are just to hard to get now.

 

[Michigan Slim]

What brand primer is that? S&B primers look like that.

Yea, but I believe 10mm has a much heavier web than 40 and 357.
It's like comparing 357 webs to 360 Dan Wesson webs.
And with that heavy web that doesn’t expand, what little primer flow is going happen will flow into the only place it can go.

I form 22 Jet out of 360 Dan Wesson brass for that reason.
