There also may be a type of crimp that is a a shiny sleeve Or ring around the outside edge of the Primer between the primer and case 

These are the two types I have encountered!

 

Yep.....the primers do appear to have a "ring" around them.  And, since this stuff came from a LEO range, I guess I will just assume that the primers are crimped.  Thanks, again.

The pockets should be swaged (but only once) to remove the crimp (or staking to some).  Not too difficult with the right tool.  I used to use a hand cutter but have switched to a press mounted swager.  It seems more repeatable and you are not cutting away some of the brass.
