Getting my head around the pocket crimp and Dillon Super Swage 600.

[Samgotit]

How is the crimp put in place for .223? I know there are different types of crimp, but how is the standard military crimp made?

I assume the crimp is on the surface of the primer pocket only; i.e, the crimp does not extend down into the pocket?

How do you set the Dillon Super Swage 600 to precisely remove the crimp without going too deep? Can you go to deep.

Thanks.

The depth is not changed. I believe you adjust the shell so it just clears the assembly (permitting removal of the case) and then swage the primer pocket. I have had the shell too far away and the crimp was not removed. I knew it wasn't removed because I could not seat a new primer. I don't believe you can go too far.

You can go to far. It tears up the primer pocket and can bend the rods in the super swage.

Huh! Learned something new! I stand corrected.

I found that the small rod (the one that pushes against the primer web) is to small and can damage the primer pocket.

I turned down the large rod to just fit the fired/expanded neck of the shell and haven't had any problems.

If you read the instructions Dillon recommends sorting by headstamp stating that the web thicknesses vary from brand to brand. If you then set the depth of the swage to leave only a small radius on the opening to the primer pocket, swaging only cases if the same brand, the swaging will be uniform and just the right depth. Adjust again as you change to another headstamp

As for "depth of crimp", I have found that some crimping actually deforms the walls of the primer pocket some, creating a slight "hour glass" shape. Swaging has to be deep enough to remove this too. I have found that the most irregular crimping has been on the Federal cases I have processed.

Thanks all.

As for how a crimp is put in place, anyone have any idea what the mechanical actions is. What type of machinery is used?
