Default K98 miss firing.

I've got a K98 Muaser, given to me by my best friend for a wedding gift.After many days at my local range getting to know it. I took it to Camp Perry to shoot in the CMP matches and it started miss firing. Needless to say I bowed out of the compitition. When I got home, I broke it down, the fireing pin looked good, the spring looked a little worn so I replaced it. Still wouldn't fire all rounds, I then replaced the pin just in case, and it still only fires about half the rounds I put in it. Could this be the ammo I'm using? Or a problem I'm just too close to see? The head space seems right, there's no damage to any brass shot through,and no tell tale sights to make me think it might be off.
Thanks.

Striker channel in the bolt. Very likely gummed up. I see this in all sorts of semi-auto handguns and high round count bolt actions (mil surps) Remove the striker and flush the inside of the bolt with gun scrubber. Use a bore brush to scrub the heck out of it. Follow up with a bore mop or slotted tip and patches. Use a flashlight to visually inspect the interior to insure it is spotless. Reassemble, but leave dry. Oil is the main culprit here. Brass shavings are the second concern.

Ammo? Reloads, surplus?
Primer strikes on ones that fail to fire. Deep or shallow?
Inside of bolt. When you first got it it was ok. After you shot it a lot some crud could have broken loose and is interfering with the firing pin.
That's all I got.
What Robo said.

1950's Yugo ammo is notorious for miss fires. What kind of ammo?

You might have to strike the round twice.

Chamber a round, fire. Click but no boom? Raise bolt handle but don't eject the round, just reset the pin, fire again.

I had a thousand rounds and I had to do this for every one. Kind of a PITA but it went boom.

I had the same problem with an M-48. With various surplus ammo it would fail to fire 1 rd out of every 5.

I took the bolt apart, cleaned everything spotless, firing pin protrusion was spot on. I couldn't find anything to fix inside the bolt.

So I ordered a new heavier Wolff firing pin spring, (striker spring). Factory was rated at 20# so I bought a 26# spring to give it a little more force. Solved my problem, runs 100% now.

This is just what I ran into, don't know if it would help your rifle? Need to know more about the type of ammo you were using like they asked above. Good luck, Ken

Thanks guys, heres what I've done so far. I've replaced the firing pin, replaced the spring with a 24# one, striped and cleaned until I'm blue in the face. The strike marks on the primers are deep, the same as on rounds that do fire. I've only got the current ammo that I bought at a gun shop, that was my next step, replace the ammo, but they only sell the Yugo stuff. So I'm waiting for some to come in the mail from Aim Surplus. I'll keep you all informed.
Thanks for the help guys. Truly appreciate it. I'll let you know what happens.

If you are getting deep indents in the primers and they are not going bang...You have an ammo problem. When you say "Yugo" do you mean the modern PPU ammo? It generally has a good rep, but problems can occur. Bad batch of primers or improper storage can be the cause. I would take it up with the store you bought it from.

Nope I use surplus ammo in all my surplus guns lol. I'm thinkiing its the ammo also, I've got more ordered from Aim, but it takes a couple of days to get here, meanwhile I'm taking the remaining rounds back to the store where I got them.
Thanks for the great advice guys.
