Too much crimp

    Could too much of a tapered crimp affect the hammer strikes,as in light strikes on the primer?.I am using a semi-auto.380ACP.

    Theoretically it could let the case go too deep into the chamber and cause them, but usually it catches on the extractor and fires just the same.

    99% of light strikes in autos is a primer not seated all the way.

    If it isn't those two things, look at springs, but I bet seating the primers better fixes it.

    When I started reloading I had this problem and had used small rifle primers instead of pistol primers. Only half of them fired, had to take apart about 20 rounds. Learned to double check and put things back in the proper box after use and not depend on memory.:eek:

    My CZ-PO-1 loves Rem. 6 1/2 large rifle primers. During my primer shortage had to sub for small pistol primers, in 9MM. All went well..

    I agree with walkalong: Primer Seat or Springs.

    Do they fire the second time they are hit? If so, the first hit may be 'seating' them so the second hit will fire them.

    Too light of a hammer/mainspring will give light strikes. They usually show up first in the '
    harder' primers like CCI.

    Federal Primers will fire with very light hits.
