    Has anyone else had the problem of the rims cracking off of A-Zoom snap caps? I purchased a set of .38 special snap caps back in December and so far two rims have completely cracked off, one is ready to go, and cracks are forming on the rest. I have had a set of 9mm snap caps for a year and those are fine. I can put up with one broken snap cap, but the whole 6 pack breaking? Does anyone have any experience with A-Zoom's customer service and possibly getting a replacement set?

    My 9mm set has burred the edge badly where the "bullet" seats into the "brass", due to the 9mm headspacing on the case mouth. My .38 A-Zooms have lasted much longer.

    As nice as A-Zooms are, they are only aluminum and do take a beating with a lot of dry firing.

    Sorry to read this, I am still on my first set of A Zoom caps in every caliber. No experience with their CS. The firing pin should be hitting silicone, not the metal. Are they on any warranty? If you bought yours brand new, not repackaged by someone on eBay or at a gun show, by all means call them for a replacement.

    I don't know if they have a warranty but I could call. I'm using them in an S&W model 10 and I just though of something. Maybe the snap caps aren't reaching the "ledge" inside of the cylinder chambers that the end of the brass rests against. By this happening, the rim is being forced against the cylinder every time the firing pin falls against it. Over time, the rim breaks from the stress of being smacked into the cylinder over and over again.

    A rimmed revolver cartridge never, ever reaches the 'ledge' in the front of the chamber, ever.

    That 'step-down' is the transition to the chamber throat, that is there to align the bullet with the forcing cone in the barrel.
    Nothing more.

    It has nothing to do with case support, or cartridge headspace.

    The case mouth in a revolver cartridge should not reach it, and doesn't.

    All the energy from the hammer hitting a snap-cap is absorbed and transferred to the cylinder face by the rim of the case.

    The OP's snap-caps are breaking due to metal fatigue from repeated use.

    Whether or not that is due to a bad lot of aluminum snap-caps or not is dependent on A-Zooms reply to his complaint.

    But the revolvers chamber throat shoulders at the front of the chambers has nothing at all to do with anything.

    I'd contact A-Zoom - the worst they can do is say "not covered"

    Please update with their response, I've never had trouble with their products, myself, and mine get used fairly heavily.

    I just sent a ticket, I will post again when I get a response back from A-Zoom. This OP will deliver.

    Mine did not exactly break...

    I bought some in 8mm for 'helping down' the bolt on my 42 so that the bolt was not going forward on an empty chamber after firing the last round on the belt.

    This is what one of them looked like after twenty or so belts.
    Safe to say that the bolt aggressively chambers a round. LOL:)

    I won't be asking A-Zoom for new ones, but you should. They make a good product if used within their design perimeters.

    It seemed like a good idea at the time, JT

    Don't tell A Zoom but there may be a small print somewhere that disclaims dry firing as the intended use. I vaguely remember someone (them?) stating the product is for resting the uncocked firing pin, hammer down. If I remember incorrectly, so much the better for OP.

    I found that on their website, so I should be good if all I was doing was dry firing with them.

    I have A-Zooms inseveral calibers for AR's, bolt actions, semi p[istols and revolvers. never had any issues aside from some scratches on the body from cycleing them through Autos for malfunction drills.

    They said that I can return them for evaluation and they will be replaced if the rims are failing.

    RC,

    What type of Snap Caps do you recommend for .45, .38/.357, .22 LR, .223 and 12 gauge?
