Oh boy...two hole primer pocket

[Vet66]

I did pull down all the loaded rounds from this run. Yes the depriming pin was bent and, for some reason I did not change the shell plate on this Dillon 650, I still had the #1 mounted when a #2 is required. My bad.

Man, that's the weirdest thing I've seen. The Dillon/RCBS die stuff must be he|| for stout or the Starline brass very soft or both! I've pulled or broke pins on undersized flash holes much less punched a new hole!

Those in the pictures are normal brass that has had a 2nd hole punched through from a bent pin that did not align with the center. The brass is now toast

Me too!

Oh it is, it is.
I once forgot to reset the rest in the Dillon Super Swage. The first round felt "odd" as I worked the lever, so I stopped & looked. I had swaged a second primer pocket overlapping the original into a figure "8". There was absolutely no damage to the Super Swage & even the brass was supported well enough that the case wasn't deformed.

As for that primer pocket....

Did you ream or 'uniform' those primer pockets?
That chatter in the primer pocket is not typical of Starline cases, in my experience.

I have to agree, what is that extra ledge in the primer pocket and the chattering at the bottom?

No wonder you were able to punch through the side of the primer pocket, someone's almost drilled clear through it. Any press and primer punch would punch a hole through the bottom of that primer pocket, no matter who made it.

If you didn't drill those out and you bought them from Starline that way, you need to send them back to Starline, They make some of the strongest brass on the market.

Those aren't safe to use at all.

I wondered about that, too. Thought maybe he cleaned it out just to show us the two holes more clearly. Pistol rounds are not normally fired at distances long enough for primer pocket depth uniforming to make a measurable difference in accuracy. Indeed, that could actually make ignition less reliable as many revolvers don't hit primers as hard or as deeply as rifles do.
