OK, I have a .270 remington that I'm getting light primer stikes from and can't seem to figure out what to do. I thought that it might of been the spring or the firing pin itself. So I replaced both last week and still have the same problem. This gun is only about 1 1/2 years old. Anyone one have any ideas on what this could be?

P.S.
I have also tried different ammo and that doesn't seem to help.
 
.270 xcr and I have put about 500 rounds through it since I have had it. Bolt seems to be fine, no excessive play or rubbing.
 
I'll go along with the excess headspace thing.
Do you reload?
Decap and reprime ( no sizing) a case or two that have been fired in your rifle and check the results.
 
Ok, I went home and check the cases for stretched ring and found all cases to be fine. I'm a reloader but I'm having this problem with both the factory and the reloaded ammo.

I saw an article about putting tape on the back of a case to find out if I have excess headspace. But I don't know how many thousands more would be too much headspace.

I did check with a depth gauge from the back of my bolt what the differnce of the firing pin with a case in with a light striked primer and with no case. I found that with no case the firing pin is about 0.010" deeper with no case in. Which would make me thing spring problem.

Take the firing pin assyembly out and look inside the bolt body. You could have something in there that is causing the firing pin to slow down or stop short. Grease, oil, or dirt, The new Rem. (yours) have the tighter fitting springs and flutted pin, check that to see if something is hanging up in there. Al
 
Just figured out the problem. It was the Timney trigger that I installed when I first got the gun. For some reason the older ones have to short of a sear. As soon as I put the a factory trigger back in the problem went away. Why it worked fine for about a year and then started having problems makes no since to me.

BE CAREFUL WITH OLDER TIMNEY TRIGGER FOR A REMINGTON 700!!!
 
Primer failures

OK! so what you had was the firing pin assy. was not cocked back far enough to get a proper spring tension to strike primers. I've seen a few guys that tried to speed up the firing pin speed by taking metal off the firing pin plug and wound up with that situation, took a while to figure it out until I noticed the end had been ground. Changed plug and de-bubbaed it. Al
