Remington 700 picks and choses when to fire

If the bolt face was "TRUED" prior to barrel work and headspacing, The firing pin will stick out further. I only remove less than 0.001 most of the time, But I have seen some "Hack" jobs that removed way too much. Check firing pin protrusion.
The bolt face was trued on barrel number 2. This is barrel number 5 so I would think he would check the bolt face each time. His barrels always shoot .1 or less. He rebarreled my .243 and 7 mag and both would shoot .03 @ 100 yds.
 
I think you're right. I didn't think the caliber through.
It's just a simple wildcat round. Take a 300 win mag and neck it down to a 7 mm. Thus the 7x300 win mag. About 30 fps slower than a 28 Nosler but you get twice the barrel life. A very accurate round for long-range hunting.
 
Where did you find that pin? PTG sells all the parts except that one. OOS at Numrich.

I got it from Midway USA, but it's now discontinued. This supplier has them:

 
BTW, when you disassemble the bolt, go to local hardware store and buy a hitch pin like this, right diameter to fit into slot so you just snap this onto bolt body and the flat side will lock into place in the slot. I am sure NONE of you had a dime flying around your bench or maybe just I am "lucky" to enjoy that scenario. They come in every size so you can find one.

ha ha - I keep a dime and a quarter on my bench for this. :)
The dime is for locking the striker back, the quarter I put in my vise, with just a bit sticking out, and use that to pull the cocking piece back, instead of gouging up the edge of my bench.

Yeah, makes a lot of "cents" but I had dimes flying all around, heck they almost made change from bouncing across bench....
 
Springs, take a "Set" over Time, especially IF, Bolt is Cocked for, extended Periods,..
And, Buy, a Timney or Jewell Trigger and
Throw, the Factory Trigger,.. in the Trash Why?I have never had any problems with a Walker trigger.Of course some folks have no idea how to set them ,clean them and make them dangerous because they are Bubbas.
 
Can't quite tell if the action is open or closed. I tend toward it's closed. Not sure if it's pump or auto. I feel it's a pump. That doesn't matter much. Never look down a barrel with the action closed to start with
Contrary to old dive's tales about springs wearing out under tension or taking a set, that doesn't happen. The same old myth has been going around for years about magazine springs. Metal fatigues from being worked so if the spring is weak it is likely from the 5000 rounds that have been fired through it.

I would disassemble the bolt and put in a new firing pin spring and firing pin. It wouldn't hurt to clean it too.
I've had magazine springs go bad by leaving round in the mag. I don't do that any longer. I may only put in a few rounds in instead of a full mag. Remember the count too.

If you have access to another.308, I would take the rounds that failed to fire, and try them in another rifle. If they fire, you have a bolt spring problem. If they again fail to fire, the problem is with the loads.
I never saw where you answered the question of whether the loads were factory or hand loads. Factory, I would change brands of ammunition, if possible. Handloads? I could write a whole page on what could go wrong!

The ones that failed to fire I ejected them. Waited 30secs or so then loaded them back into the chamber and they fired.I'm leaning towards the primer slid forward on the first strike then fired because the primer was seated properly
 
Strikers (firing pins) are generally OK but their springs take a set and get shorter delivering less striker energy and velocity.


Go here and you will find they generally make 3 springs for most rifles, FACTORY , stronger spring and a much stronger spring.

I generally get the middle one.

Disassemble the bolt and measure the free length (uncompressed) against the one you just bought and you will probably find it to be shorter.

Weak spring not only contributes to misfire, but will also contribute to inconsistent ignition. The latter is detrimental to precision.
