Browninghunter the best way to tell if primers are crimped is to have a primer pocket cleaning tool, and primer pocket reamer. If the cleaning tool does not go in then the pocket is crimped. A few twist with the reamer, and the crimp is removed. All of my .223 Brass with the execption of 40 pieces of PMC is range pick up. They seem to shoot prety much the same out of my Savage bolt action.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
