Blown Primers Damaged My Revolver?

    In 2007 I bought 4 boxes of Winchester Super X .357 Mag 157 GR JHP

    Today I tried to shoot a box and about 30 rounds into the box my S&W .357 jammed. The firing pin was melted and fused to the primer.

    It turns out my ammo was not Winchester it was reloads. The primer melted my firing pin, I have to send it back to S&W to fix. Below is my order info.

    What would you do if you were me? I am PISSED :cuss:

    How can you prove it was reloads?

    you're just now using ammo you bought in 2007? Did you inspect all of the boxes when you received it?

    Maybe sometime during the past 5 years, gremlins got in and reloaded it all. Gremlins are sneaky little things.

    how can i prove they are reloads? 1) There is no sealant, 2) Some of the primers are set above the level of the cartridge, 3) THEY melted the firing pin and ruined my gun

    that's how i know

    What sealant? Most manufacturers don't apply sealants to their cartridges.

    That kind of stinks, as a quality-control issue, but doesn't prove these are reloads.

    How does a primer melt your firing pin? Are you saying that the primers blew out? Or that they cratered and flowed into your firing pin aperture, jamming the gun? Or is your firing pin literally damaged? As it stands the statement doesn't make sense. Primers don't even get very hot. No where near to steel-melting temps. If the fire contained by the cartridge on firing was hot enough for long enough duration to melt steel, your barrel wouldn't be long for this world, either. So something else is going on.

    Even one primer blowing out is not enough to damage a gun. Most of us have had it happen from time to time and the guns still work just fine.

    Have you got the gun apart now? Can you take pictures of any of this? If the gun is "ruined" there must be some physical damage we could look at.

    Have you contacted Winchester with the part numbers and lot numbers of the ammo? If there is any measurable issue with the remaining ammo, they'll replace it, and probably throw in an extra box or two for your trouble.

    Right. If the primer melted the firing pin, then the primer and cartridge would have been a mess before the firing pin melted.

    Rod, you have pics to show us, yes?

    You can have popped primers cause gas cutting to the firing pin or its orifice.

    I suspect what's actually going on is Winchester is having QC problems (again) and thier ammo caused his revolver to malfunction. Not that there is a conspiracy to substitute crap reloads for new ammo.

    In 30 rounds? Ok, I doubt it, but maybe.

    So, lets have a look at the cases. Did 30 primers actually pierce and blow through? If so, I'd also want to take a look at the projection of his firing pin. Becomes a "chicken and the egg" sort of question. Primers getting pierced is generally a sign of the FP being longer than spec.

    Very likely so. But "causing a malfunction" and "ruined my gun" are two very different things.

    I want to see pictures too. I have been a victim of crap factory ammo myself. 1 box of Remington .45acp had 1 round that had no rim and a box of Tula .40s&w had a squib load that stuck in the barrel (boom, boom, pop, STOP!). Is the head stamp the same on the troubled rounds? It does sound like a quality control issue with Winchester. Although, I would not entirely rule out someone maybe pinching a few rounds of ammo from work (Sportsmans Guide)....Maybe replace them with reloads? I am not suggesting that occurred in any way and it is VERY unlikely, but stranger things have happened.

    This one doesn't pass the smell test.

    There's not a reload on this planet hot enough to MELT a firing pin. Just can't happen. As someone else pointed out, gas & fire erosion is real, but it takes a lot more rounds than this, and causes tiny pits to develop over a long period.

    Well, the OP hasn't been back since Monday, and without pictures and more information I don't see anything more we can do here.

    I'm going to close this for now. Rod, when you do get back with some pictures, please send me a PM and I'll open this back up for further discussion.

    Sorry I was late responding, I am really tied up with work a lot these days. I have pics to post that might help identify what the problem was. I do appreciate the members taking their time to respond.

    These pics show a few of the fired rounds and the remains of the firing pin, as well as different views of some unfired rounds. The gunsmith I took the gun to said the rounds were reloads, and that they damaged the firing pin to the point that it would no longer work.

    Is his analysis correct, do you think? If so what should I do? It seems wrong that factory ammo (or reloads sold as factory ammo) would damage the gun.

    I bought the gun about 5 years ago. I've only put about 500 rounds through it.

    Am I correct in reading the two on the right as grossly over pressure?

  19. rod5591

    rod5591 Well-Known Member

    last pic. the gunsmith says they are likely reloads......

    thanks for your input. I am planning on sending the gun back to S&W since the gunsmith says that S&W firing pins are not available except through S&W factory...is this true???
