    I have not lost a Jewell trigger to pierced primers , but have temporarly lost function due to powder and metal flushing thru the trigger.

    Swd...Good idea. I did a search, found couple who had or heard of it happening but mostly asking if it could happen. I bet there are a whole bunch more non competitive barrels out there than there are broken sears. Now with my luck I will get a broken sear this year.

    Think maybe parts wired out of plate stock VS. investment cast parts might have something to do with it?
    And yea I've taken bolts apart during a match to dump all the discs out.
    Old Jewell's are golden.
    After some thought I was running Ben Burns 3 lever conversions back in those days.

    I do use the old jewells for sure. Anytime i sell a br rifle it gets a brand spankin new trigger for its new owner- makes it an even better deal right?

    Yes, it can happen but is far from a certainty. I've pierced a bunch of primers over the years, mostly while ff cases and I've never lost a trigger to it, personally...but I've seen it happen to others.

    Many thousands of rounds fired and I’ve had exactly 1 pierced primer.
    It broke the Jewell. $60 or so to repair.

    I think action/bolt design is an important factor in this, as well as the case used, i.e., large flash hole and possibly fp tip diameter. Some actions vent gas from the bolt better than others for one. What happens is, gasses enter the bolt body, driving the pin rearward and it then flies forward into the sear bar of the trigger, breaking the trigger. I think the way the bolt manages the gas plays a major role in whether you break a trigger...but then again, so does luck.

    I knew something was up when I saw smoke out the vent hole.

    I've had a badly blown primer in a Rem 700 that blew the extractor recess off the bolt face, forced the floor plate to fly open, and disabled the trigger sear engagement. So yeah, a blown primer from excessive pressure can definitely disable a trigger.

    In my case, I just cleaned the trigger and re-adjusted sear engagement and it worked fine.

    But the bolt face had to be machined out and bushed plus a sako extractor installed before it could be used again.

    I broke a Jewell with a popped primer in a Dasher. Send it back to Jewell and they'll fix you up!

    I broke 2 Jewel triggers like that ,they charged me like 70 bucks each to fix them..

    In another action I have blanked several primers with no damage to the trigger, idk maybe it diverts the gas pressure out different.

    Broke a Jewell FF Dasher brass using Federal primers. Another great reason to shoot the 6BRAI over the Dasher--much easier to make good brass.

    Good Shooting
