what primer to use?

5mmgunguy
I have an SKS that fires every so often on bolt closure...I am using Federal 205 SR primers...is there a SR primer that is harder that will not slam fire. Thanks.

    CCI makes a milspec harder rifle primer. There are also update kits to put a spring on the firing pin to reduce the chance of this.

    As jonk said, CCI mil primers or Wolf "magnum" primers. The Wolf magnum primers are not magnum charge wise, but they have thicker cups to prevent slam fires.

    As mentioned above, CCI #41 arsenal primers.

    Interesting, are you sure there is not a problem with the rifle?

    No problem that I can see.

    5mm- if you have not already broken down the bolt, you may want to get some good spray gun cleaner, and flush the daylights out of the firing pin channel. SKS are known to have dried grease, cosmoline,dirt, borscht, nuoc mam sauce, etc in the FP channel causing FP to stay in forward position, resulting in slam fire. If this is something you already know, please excuse lecture.

    Firing pin channel is clean and the pin moves freely. CCI primers sound like the fix. Thanks.
