Thanks for the heads up. I didn't know this, but I did know that federals were more sensitive- prety much the reason I don't use them in autoloaders.

CCI primers are junk the metal used in them is too hard for alot of guns to set off, I would go to a winchester or federal primer just dont seat them to deep and besure not to crush them or you will be likely to run into the same problem.

Yup CCIs are so bad that its the primer that the US Military uses for its 7.62 ammo. If a rifle doesn't set it off, then the firing pin spring is way on the weak side. I've never had a problem with them.

well in a rifle thats a different case then a bolt action should have no problem with a CCI I was talking on the handgun side of things

From what I understand, Primers are made up of the cup, compound and anvil and are coated with a very thin moisture barrier. They are almost impervious to water and humidity. I found primers that were hidden in the back of my reloading bench drawer that I had for years, put them in some ammo just for range shooting and didn't have any misfires.
Oil is the biggest culprit for primers. Be it gun oil, skin oil or any other type.
As for CCIs, thats all I use and haven't had a problem in over 20 yrs.

Could be one of three things...contact with oil on the primer face, primers not being seated correctly(flasholes not uniform or too much residue) weak firing spring(Ruger I doubt it)

I have been using a Lee hand seater and RCBS hand seater for years and have only used Federal primers..I will look at the box nevertheless. Wouldn't there be more of a chance of crushing primers with a press setup then a hand setup based on leverage and force exerted?

The ONLY problem I ever had with primers failing to fire was due to oil! Once I figured out a way to install new primers without touching them with my hands, this never happened again.

I once had an acqaintance who had a problem with misfires with some ammo he had loaded with my tools. It turned out that he had omitted the powder charge from some of them! The bullet bases were very black!! But they were still in the case! Good thing he had good neck tension, thus preventing a stuck bullet in the bore, because SOME of his loads DID have powder....

One more thing that could cause a miss-fire is your headspace my be off...

tom, it could be you have a sticky firing pin. Just this past Sunday my friend and I were out shooting and he brought his new Savage bolt and his Rem. pump out. During our last session a few weeks ago, he had a mis-fire with his savage. He had one again this weekend. The primer was indeed dented. I took that round and put it in his pump and it fired.
When he got home, he flushed out his bolt on his savage and found that it was 'gummed' up. He never cleaned the guts of the bolt.
I would try flushing your bolt with gun scrubber, let it drain, flush again, drain - then LIGHTLY oil. Use just enough oil to put a thin film on the parts to prevent rust. (WD40)
