Help! Problem with redding comp shell holders and redding type s fl sizing die

[jb41291]

Went to size some of my hornady 6.5 cm brass and bump the shoulder back .002". Brass is once fired with a cbts measurement of 1.501". Started with the .010" shell holder and screwed the die in until it made contact with the shell holder. With the .010 shell holder, i ran a lubed case into the die then measured the cartridge base to shoulder. The shoulder actually went from 1.501 inches to 1.504. I sorta expected this. Then started stepping down. I then inserted the .008 shell holder and no bump. Then the 0.006 no bump. I noticed as i got to .006 and inspected and measured the case i noticed it collapsed below the shoulder. That is when i stopped.
Idk what I am doing wrong at this point. Any help would be great. Thanks

Picture of this colapsed shoulder would help a great deal.

Is it completely folded on itself like the start of an accordion or just a little dimple?

Looks like too much lube was used

That looks more like excessive case lube than a collapsed shoulder.

I did not know that was a thing. I will chill a little on the lube.

It is hydraulic pressure because the fluid doesn't have anywhere to go

My mind is blown right now. Hahaha i appreciate the help guys. I'm glad i will not be reloading these cases. Just sizing them to make a chamber length gauge and a modified case for bullet seating.

It won't hurt to load them and shoot them. The pressure will blow it back out and you will never know. Most of us have all had it happen at one point.

Yeah, load them up-dent no problem.

... and those that haven't own a stuck case remover.

Dents don’t cause stuck cases

I think he means sticking cases from lack of lube
