    Cool Bullet Setback ..........

    Went to the range today with the purpose of shooting my primary concealed carry guns.

    The Glock 23 and Glock 36 were flawless with mixed FMJ's and Speer Gold Dot and Remington Golden Saber carry ammo as always.

    When I went to shoot the Diamondback BUG the first rounds were Speer Lawman FMJ. One shot and then a failure to feed with the round lodged halfway in the barrel at an angle. Stripped the mag out and the round came out with the bullet setback in the case about 1/16". Fired two more rounds and again a failure to feed with the same results as the first with the bullet setback in the case.

    I replaced the FMJ with Speer Gold Dot and fired two flawless magazines through the DB. Went back to the FMJ and the first round I attempted to chamber was a failure to feed. Replaced the FMJ with Gold Dots and again no problems.

    I have fired Lawman FMJ through this gun in the past with no problems. This was a new box of ammo and I am wondering if I got a bad batch.

    Thoughts and opinions welcome.

    compared to the GD and the GS is the lawman bullet shaped different ( perhaps longer and flat sided, different ogive)?
    if it is the only brand of ammo the gun dislike, don't use it. it is good to know why something does not work, but sometimes just not using it is a legitimate answer.
    Be aware, be deliberate in your actions and be accurate.

    You went shooting without me? Well, then call your issues Karma.

    Odd that suddenly a previously "good" brand went south on you. Possibly the batch, but odd all the same. At least you know it's just an ammo specific problem, not a "gun" issue.

    While probably not the case in your situation, setbacks can also happen as mag springs weaken but recoil springs are still strong. In this case it sounds like it's ammo specific.
    I'd give my right arm to be ambidextrous.

    The Diamondback has a dual recoil spring setup and is a bear to rack the slide being so small. It absorbes recoil extremely well and this may have been a factor with this particular lot of ammo. Thanks for the reply.

    It sounds like an ammo issue to me. But to be on the safe side, next time take OldVet along.

    Bad factory batches can happen

    I recently bought 2 boxes of Remington 158 gr LHP .38 +P that had zero crimp. I ran them through my crimp die. You may want to check that angle.
