    I have recently been using Cheddite primers. I notice that some of them are being pierced by my firing pin.
    I shoot a K-80, has anyone else seen this problem?

    Paul7177 I have shot a lot of the Ceddite primers. Thousands and no pierced primers. I have a good friend who has a K-80 and has pierced Cheddite primers. I have heard Cheddites and K-80's don't get along. I have also never had a failed Cheddite primer. Perhaps others will ring in with their experience. It will be interesting to see if the K gun thing is true.

    The older K-32's have problems with them as well. You need to stop useing them quickly before you need a new firing pin. Break-em all. Jeff

    Paul, if you are piercing primers you may run the risk of sticking a firing pin in the primer, which may make it difficult to open the barrel. When force is applied to open the gun, this may break the firing pin. Bob

    3 Browning XTs and more pierced Cheddites than I care to remember. The only time I bought those things I spent every penny and more of what I "saved" over Winchester primers just replacing burned firing pins.

    The Cheddite primers seem to use a brittle steel for their primer cups that tears rather than stretches when the pin hits it, and the fact that the Browning pin hits the primer from the above and side makes things worse.

    Every Cheddite I pierced had the entire cup deformed by the firing pin whereas Winchester primers show just one clean dimple and the rest of the cup is unchanged. The Cheddites also deformed in the direction away from the direction the Browning firing pin hit them. With the Winchester primers it is impossible to tell which direction the firing pin hit from.

    My XTs bottom firing pins all project no more than .062" from the receiver face when pushed from behind so the pin is not traveling too far. These primers are definitely no bargain.

    Do I understand correctly that Rio has Cheddy primer?? I stopped using Rio because of this problem. Yes, K-80. (Added, this was older shells produced outside of US, going back maybe 5 or so years)

    This seemed to work till I finish all my Rio ammo. Any miss-fires, I spray oil in the flash holes and remove stock and spay oil on the back of fire pin mechanism -- contiue on. Firing pins become burnt probably adding to the problem, but why change until all the ammo is gone. Then plan to annual the gun and you will have new firing pins. I did pull the firing pin block one time thru this process. Good luck!!

    Add my name to the list. I (shamefully) bought some Cheddites to reload some "practice only" type reloads to save some money on loading as I shoot a lot. Several have had pierced cap primer caps result upon firing (maybe 25 or 30 out of a sleeve). When this sleeve is gone I plan to load only Winchester 209's exclusively. I shoot a K-80.

    Now you know why I don't use Cheddite primers. Had this problem over 12 years ago.

    This is what my Perazzi does to cheddites. Never had even 1 winchester or fiochi punch through. It was happening on 10 out of every 25 shots. Sold the lot.

    Wheww!! Sure glad I have only used Winchester 209's to reload with! At least I have never had any problems with the Winchester primers in my old MX-8.

    No, Rio uses their own primers: metric in size and a tad larger than Cheddite.

    Put me down! K80 shooter who saw this problem about 5 years ago and switched over to Win 209's and never looked back.The primers are junk and hard on firing pins.Save a couple of $ now and pay big time later on- no thank you!

    I know all about primer difficulties. Owned 3 Ljutic Dynokics and it was almost endless getting it fine tuned for primers. They have a huge spring for the thrust hammer / firing pin set up and would blow through anything which wasn't the correct depth. Other times I had Failure to Fires; nothing like running along on HCap at a large shoot back then and getting 3 FTF's on the third trap. Great guns otherwise.

    1) Get a sample of different primers and line them up. Hold a steel flat edge (small steel ruler or blade from a box cutter) across the bottom and you'll see that the metal "faces" are flat and not as deep. Also, if you use a micrometer to measure their diameter, you will find them a little larger. Thus they do not always set as deep, especially on the first reload. Also hold the edge up to primer on your loaded hulls and see if they are set deep enough.

    2) Not all hulls accept them the same, Plus, Federals for example will bow in a little. Gun clubs and AA's usually stay pretty solid. The trick with the Ljutic I had was to adjust the firing pin length using very thin shims inside the hammer. The pin was supposed to extend about .060", which usually worked well, if the primers were properly set in the hulls. Trick, find a flat washer .060" thick and drill a small hole in it. Set it over the firing pin to check the extent that it's protruding. If it's too long you may want to shorten it.

    Summary, I had to basically set the gun up for one load / hull - primer and stay with it. ( I am now happy to have a Ljutic One-Touch which has a floating firing pin )

    Sometimes you get what you pay for (or didn't pay for). I personally have not had ANY real troubles with Cheddite primers. I don't shoot a K-Gun or a P-Gun, so I can't say about them. They have worked well in every gun I have fired them in and I have never noticed a primer perforation with a Cheddite primer.
