    Light primer strikes?

    I had about 20 rounds out of 100 not go off n all had a light strike on them.

    Im using Precision Delta 165gr .40 bullet.

    50 were using 5.8gr of Unique and 50 using 5.9gr of Unique.
    All with an OAL of between 1.115 to 1.120.

    I feed each one in manually n they shot

    Thanks
    Greg

    If they shot the second time it most likely high, insufficiently seated primers.
     


  3. Is the gun stock? If so, it is most likely a primer seating issue.

    Gun is all stock G27

    What's weird is on Sunday I shot 50 rounds no problem

    So is it because it was seated too deep or not deep enough or just not seated correctly?
     
  5. Not deep enough. The first strike fully seated them and the second strike busted off the primer. Most likely.

    Well even after I loaded them back in the mag they didn't shoot.
    I had to manually load each one in the chamber before they shot

    So still not deep enough seated issue?
     
  7. Not sure. What brand of primers?

  9. I am still leaning,seating issue. Are you primers seated below flush with the case?

    You didn't change any springs out?

    You know... there IS a thread about "Light Primer Strikes" just below this one that's been going on for a week?

    Discussed has been:
    Primer seating
    Light striker springs
    CCI primers being harder to ignite than Federals

    If they shot after you loaded them by hand you most likely chambered them by pushing them in with thumb pressure. If your bell/flare is slightly oversized or your OAL is slightly long slide/recoil spring pressure my not be enough to fully seat the round. When you tried to fire them a second time from the mag the pin strike may just be pushing the round further ahead in the chamber.

    As an aside... are you really going to take advice from a guy that starts his screen name with the word, Shady? :whistling:

    Did the rounds go all the way into battery? Or did you have to bump the slide?
    Loading one round at a time by putting the round in the chamber and closing the slide is a good way to break the extractor.

    And is he SLIM?

    There have been some reports of bad batches of Winchester primers recently. Some shops around here have been sending whole lots back.

    Use good primers (preferably Federal) and report back.

    I used the same primers with 100 rounds of 9mm and everyone shot fine.

    I didn't put any pressure when putting those into the chamber.
    Just dropped them in n closed the slide

    Im betting like u said the OAL was on the long side for those rounds
