Thread: Word of Warning HMR Users

  1. #1

    Word of Warning HMR Users

    I know most people are aware of this and it has been covered many times, but if you get a miss fire, hang fire, click of the firing pin or anything that is unusual, wait 60 secs keeping the rifle pointing in a safe direction, then.

    REMOVE THE BOLT AND CHECK THE BARREL FOR OBSTRUCTION.

    This was highlighted to me last night again when lamping.

    Shot one rabbit, cycled the bolt for the next, then 'click', there was no noise except the firing pin BUT the primer/powder had produced enough power to lodge the bullet in the rifling.

    Obviously if I hadn't checked the barrel and fired another round the results would have been severe.

    As usual this was cause by a split in the case neck causing moisture ingress.

    After checking 300 rounds this morning over 30 had split necks!

    Please be careful...

    This is the main reason I went for a .22 hornet instead of the HMR + i can reload the Hornet

    But with wider considerations and for perhaps those setting out on their in-the-field shooting career, let's add (as the 1st stage of a misfire) "keep the rifle pointing in a safe direction and wait 60 seconds BEFORE opening the action".

    The enemy of knowledge is not ignorance, it is the illusion of knowledge.

    60 seconds and lift your head away from the action and use you thumb and forefinger to work the bolt.

    I have checked all my .17 HMR rounds and have found 8 split necks. Sometimes these are very subtle and really need a strong light and a magnifying glass to see, but sure enough you can do your own quality control. It should not be this way, but it is and should be until the old ammo is shot up. And if there is a misfire do check the barrel for obstruction.

    Hornady, but I've had split necks with Remington and Federal as well. They're all made by CCI. Also Winchester.
