    One hopes there might be some point to this?

    While it's been suggested that reading straight-wall brass for pressure signs is 'voodoo', certainly there are indicators.

    Paying attention to all results of shooting handloads, be it 'feel', chrono readings, brass condition...

    Those were pretty hot. How did the pockets fair or should I say flair........may need an extra firing pin/striker on hand.

    I don't see any flattened primers. I see signs that the firing pin hole may be too large and the firing pin might be a bit too sharp, but nothing I haven't seen from lots of guns, with factory ammo.

    No, the third photo shows excessive pressure because the primer stikes are pushed back out, hence the comment of keeping a spare firing pin handy when shooting that particular recipie.

    Well, those were my first pierced primers - at least that I'm aware of.

    I've loaded the same recipes that produced the above, and will collect the brass as I go.

    I'm curious which load's the culprit, unfortunately it'll likely be weeks before I find out.

    Great pics! My best accuracy rounds seem to lie in the middle of the range between start and max grains of powder. A Chrony is a great way to fine tune loads and experiment. Just my 2 cents.

    pics 3 and 4 definately look too hot. ive loaded some "hot 38spl" for my brothers 357 mag knowing the gun is made to withstand the pressure of a 357 mag and they didnt look remotely close to pics 3 and 4. in my opinion if the casings from pic 2 were mixed in with pic 1 i would say it looks "normal" to me even with some if the strikes are "cratered" i find this to happen more often when i mass reload and dump powder from my uniflow depending on powder type.

    Oops.... I meant the third photo, not the 2nd (working off an iPhone sucks sometimes) Looking at the fourth again... Wow, I just realized the primer strikes have been blown out from the inside... WHOA! :eek:

    I see some cratering, set-back, and large firing pin holes.
    I think more than one firearm was involved.
    Without context, it means nothing.

    When I test loads
    Each set starts in a labeled sandwich ziplock
    Fired over a chronograph
    Notes included for each set (bullet, powder type and amount, group size, velocity, etc).
    Set cases and notes back into the sandwich bag(s)
    Back at the workbench
    Inspect under lamp and magnifier.
    Conclusions entered into loading book notes for the future

    There's more that I do than the above, not writing a book though.

    If you don't use a chronograph, you're playing with fire

    All shot from the same gun, chrono readings taken.

    Just failed gather & inspect brass after testing each load.

    Chrono says they're warm, but not that warm.

    I've recreated the loads, and will test again.

    I suppose I was expecting a rant, since there are so many on forums these days. Something like the "I loaded these to the powder maker's middle specs and got blanked primers yaddayaddayadda" sort of thing. But I guess it's a good thing to post "hot loads blank primers" as a warning or a help to the inexperienced.

    Looks like obviously the loads are too hot for your particular gun. Also looks like the firing pin does not fit the firing pin hole in the breech face too well. You may need a new (bigger & fitted) firing pin and maybe a weaker firing pin return spring if your gun is so equipped, then start over with your load testing....

    What kind of gun were these fired from?

    Recommend a qualified gunsmith in the area?

    Should probably just buy an STI...

    what are these reloads primarily used for? just plinkin? compitition? if theyre just plinkers load them lighter and enjoy. no sense in using hot loads and usin up all your powder for plinkers

    This stubborn piece of junk, I mean gun, refuses to cycle reliably with light-medium loads.

    I've tried 147-180gr bullets, Unique, Bullseye, CSB-1, Longshot, Silhouette, #7, even 700-X (I know...).

    OAL is always around 1.258, except for the lead bullets, they're at 1.24.

    Load near Pmax and the gun runs flawlessly, back it down and FEs almost every time o_O

    im sorry about what you are experiencing . from your posts back in august it sounds like youve had nothing but trouble with this gun...maybe inadvertently limp wristing? too heavy of recoil spring? just a couple of ideas...might be time for gunsmith OR a glock 10mm... he he he.;)
