    I guess you are already fully aware of the potential issues shooting your type of platform and do check for proud primers?

    To be honest I just do a visual on my primer depth.

    Thinking about the issue I had yesterday, I went back and looked at my note book and I can see that while testing 3 weeks ago I also had 2x double fires (two rounds slam fired?) at the NZDA range while testing three different kinds of brass again...Guess which one had the issue!! RG..bugger me.
    I just went and primed about 700 rounds of the RG expecting to load them all off the back of yesterdays testing..guess that's not going to happen now, I'd rather get some more FNB to clean up and use.

    Thoughts? Sell the primed RG or throw it?

    As you don't want to use it for safety reasons selling it with full disclosure and a bolt gun only recommendation would seem to be the way to go to me-binning it seems a waste but selling it as preped and primed brass would weigh on my mind unless I was up front about it

    Get your pliers out and collapse the necks. Discarded brass has a habit of sneaking back into service.

    Edit: Mmm just saw the 700 count, oh well you will end up with a very strong wrist ha ha.
    Maybe first up put it to one side until you are absolutely sure that you are clear of the issue.

    You may be able to find someone that could use it. At least that way you could recoup the cost of the primers back. Guessing about $70,but don't know what remains primers are worth

    Rule 5: Check your firing zone

    Hi Greenie.
    If it is a problem with the primers it could be one of the following.
    1: Primers not seated deep enough due to not being pushed home when seating the primer. When the firing pin then hits the primer, some of the energy of the strike pushes the primer home into the case which then lessons the chance of the primer going off.
    The fix is to ensure they are seated flush.
    2: If you are using the Dillon 600 swage you need to remember to reset it every time you change your brass. The web thickness varies between different head stamps.
    You could end up pushing the bottom of the primer pocket back enough that the firing pin wont make proper contact.
    3: Firing pin protrusion. Google is your friend to see if that may be the issue.

    Good luck.

    Looks like some pretty decent strikes, double check that you put powder in the cartridges, and push the primers out and check if they ignited.

    Ok, cheers Simon and Savage...Question: Is it safe to remove un-fired primers? I have something like 300 or more of the suckers primed.

    Simon: I never knew that, cam you elaborate on what you said there.

    Savage: Yeah there does appear to be decent primer strikes on the rest of the cartridges.

    Gingo's I'm tempted to bin the whole lot straight in the rubbish and buy 10KG of the FNB stuff Gunworks has. Apparently the RG is machine gun whereas the FNB is ex Styer.



    The idea of not trusting ya bloody rounds to go bang is friggin unacceptable.

    Cheers

    Hi Greenie.
    Yep it is safe to de-cap unfired primers. Have done hundreds over the years fixing reloading cock ups. Just run them back through the die.

    What did you want more details on? Swaging or firing pin protrusion?

    Hi Greenie.
    I Just looking at your original photo more closely I can see a slight ring around the primer pocket of the cases in question.
    You have set your swage too deep.
    Have a read of this, page 5. It shows a picture of the issue.

    Well spotted @Simon
    @Greenie as Simon has said re live primers removal. I too have de-primed many live ones, usually due to some reloading balls up.
    Have just deprimed 60 7x57 for a mate - reloads of doubtful origin he got with a second hand rifle.
    Just wear safety glasses and be gentle.
    I also deprimed several hundred ex mil 30-06 years ago and out of them all I had maybe 2 primers go off. But of course they were crimped in and quite hard to move. Also I was a bit younger and sillier and probably just have gave them a full on tilt with the press handle! Have never had reloaded primers go bang.

    I looked over them all again and the only primers sitting/looking low are in the lot of RG that misfired, and not the other RG to the right that fired correctly. If you look closely at the bad RG row, the two top cases fired and they look good, the seven other cases in those two rows didn't and they look low, I was thinking they were low because of crush and not seating issues?
    I take your pint re setting the Dillon 600 up for each manufacturer though..good idea.

    Result is, I'm not going to use them going forward, I have had half a dozen negative comments re the RG brass and would rather just use the FNB cases.

    Cheers for the feedback guys.

    If decapping live primers, wear a face shield. Ive done a few and never had an issue but I always wear a full face shield when loading and especially decapping a live primer.

    Ive use/used FNB cases and they have been fine, I'll avoid RG now though.
