[ScottRiqui]

Remove the barrel from your gun, and drop one of the finished rounds into the chamber. It should fall freely into place, with a nice "plunk" sound as the case mouth headspaces on the ledge at the front of the chamber. (That's why you'll sometimes hear this called the 'plunk test'.

Then turn the barrel upside-down, and the round should fall out of the chamber under its own weight.

If it's not "sticky" going into or coming out of the chamber, I'd try firing them as-is before worrying about crimping them further.
