Bag of Shell Holders with question

[ahlosojoe]

I recently purchased a sack full of various shell holders includi

ng the pictured items. What are these for?
If you need certain shell holders l'll mail you one for $6 if I have it. Have a good selection of RCBS, LYMAN and LEE. Thanks for the help.

them are for swagging the primer pocket, i want to say for the RCBS but i could be wrong.

They do look like the ones that came with my RCBS primer pocket swager, I think @rickm is correct.

Yes sirs that is what they are.
I had some and they do not work with the Lee classic cast press and the cup that comes with them.
The cup was too small in diameter to fit over the Lee ram.
Of course I made a larger cup from a thick washer and some pipe.
The swagers did fit the press just fine though.

The RCBS ones did not work well for the brass I was using LC-05 .308 and crimped .223.
Pimers were still very hard to get in and i peeled brass from the pockets on many cases trying to get a primer in.
Pocket knife or case mouth chamfer tool works quicker and better for me.
