Firing Pin Travel Question

Does anyone here know how much the travel can be reduced on a Rem 700 LA before F2F issues start?

I recently had some work done on my 3pos safety shroud (Cerakoted). I had it set up perfect, but when I got it back there's too much clearance for the safety lobe and it's no longer backing the c0cking piece off the sear. (No idea how this could have happened - maybe they polished the interior surfaces a tiny bit, or something with the roll pins that hold it together??)

Anyway, removing 15 or 20 thou (max) off the c0cking piece will fix the issue, but doing so will reduce the pin fall to about .225

I wonder if that tiny bit out of spec will even make a difference. I guess I could just buy a stronger spring if I do get issues.

Anyone have experience with this or similar?

I often removed material from the cocking piece to smooth out a bit of the c oc k on closing the factory 700 has. Never had a problem with misfires. You can tune the 700 to have an extremely smooth no bump on closing. However when you take it that 'close' it is tuned to that trigger.

What method were you using to remove material?

I made a jig to hold the cocking piece at the correct angle in the vise on my drill press with a 1.5 inch grindstone in the chuck at about 4000 rpm... and fed it back and forth taking a bit off each time. Trial and error until it was enough.

Thanks guntech. I was planning a similar process in the mill.
 
I have never seen that before but yes that basically shows it

Sorry I should’ve linked it to Pacific Tool.

Great description of reducing #### on close force and an effect on trigger pulls. But only to be used for target rifles not defensive or hunting rifles. I surmise that if you’re loading and know your chosen primer will be reliable hunting might not be an issue.

Unless bear defence (has that ever come up on Gunnutz? LOL) is an issue.

I’m only talking about removing a few thou, but you’re right - I’m going to put a stronger spring on it if there are any issues with reliability.

I use Federal primers which are pretty soft, so I don’t anticipate any ignition issues.

It’s also a pretty simple and cheap job to just order a new c0cking piece and recut to a proper fit. I’m going to try and work with what I have first though.

Cheers
 
OP,
Which 3pos firing pin shroud do you have installed?

Does said cocking piece have the 45degree cross pin or horizontal(OEM) cross pin?

Check to ascertain how much "#### on close" you have prior to any modifications.

The Remington 3 position shroud safety does NOT & should NOT function as per a Winny or Mauser.

-PTG

-It is the OEM c0cking piece, but modified to work with the 3-pos safety

-The modifications were already done, and everything was working perfectly. This issue started after I sent the shroud away to be Cerakoted. They sent back the painted parts, and when I reassembled, the safety no longer held the c0cking piece back off the sear - somehow it's 8 thou shorter than it used to be. I'm not sure how this is possible, but to fix it I need to remove 20ish thou from the c0cking piece - or - buy a new c0cking piece and remachine it to the proper clearance. If I decide to fit a new c0cking piece, I definitely will measure things before I start.

-Sorry, but I'm not sure what you mean here. I didn't say anything about a Winchester or Mauser safety.
 
OP,
The OEM cocking piece 3/32" cross pin is horizontal 0300-0900 o'clock.
Using the OEM cocking piece the cross pin is milled away for the safety notch.

Purchase a new 45degree cross pin cocking piece,3/32" cross pin & firing pin assy from PT&G to complete the task.
 
OP,
The Ed LaPour/PT&G 3 position swing safety for a 700 can NOT be disassembled unless the pin holes were drilled thru prior to assembly.

You quoted .008" difference from before & after a paint job of the shroud & want to remove .020" from the 45degree angle on the striker??

The Winny/Mauser reference went over your head.

Seek a professional.

I’m not sure I follow you here.

Anyway, it worked out exactly as I expected. Stoned 20 thou off the c0cking piece and it functions absolutely perfectly again. The safety lever pulls the c0cking piece about 12 thou off the sear and returns it reliably every time.

Took it to the range and put 20 rounds through it. All good now.

I could take a little more to get the recommended 15-20 thou, but I can’t think of a good reason to do anything more here.

Thanks everyone for the advice.
