Which firing pin spring ?

[rmist]

I want to replace my Rem 700 firing pin spring. Which replacement spring is better and why ? The one in it now is all twisted and rubs the bolt body as normal. This is a 223 rifle if that matters.
Thanks again,
Rmist

It is normal for firing pin springs to twist and rub the bolt body and pin shaft - and these springs rarely require replacement.

If you get a new spring, it will do the same because the springs are long and thin, and cannot support themselves.

When compressed, they will bend and lean on anything they can. NO firing pin spring is self supporting.

I thought the Tubb and PT&G did not have all the twist and rub the bolt

rmist, that was my understanding, also. Never pursued the matter, to find out, though.

Look at the tubbs you tube videos and look for the tubb firing pin spring one.

Remington springs were a very close fit to their pins for many years - the pins weighed 860 grains.

In 2000, Remington introduced a much lighter pin that was thinner - it weighed ~450 grains and decreased lock time by approximately 50%. But people were upset because the spring curled and rubbed the sides of the bolt - Remington got so many complaints about something that was better, but cosmetic, that they went back to the old, heavier pin.

you are worrying about nothing... it is cosmetic, and not a flaw.

OK...sounds good... Leaving well enough alone !!
Thanx again

You can believe what you want, but Kelbly springs use the same spring tension as original Remington as well as the same weight FP because it provides the most consistent ignition. If lighter is better why are so many Bat's reworked by the top name Smith's building Benchrest guns? Ignition is more important to peak accuracy than most realize. Speedlocks are detrimental to accuracy for guns shot off a rest.

I agree with LH on this. Tests we have done at 1000 yards off a bench showed the Tubb springs and pins gave more vertical dispersion. Maybe Joe Salt will chime in and verify this. Springs get weak in time and need replaced for consistent ignition. I have seen good guns go from shooting great at 1000 to terrible. No matter what you did in testing you couldn't get the vertical out. Then I seen new springs put in and the gun came right back to shooting good. Some of the old ones were as much as 1 inch short from being compressed all the time. Some actions and guns are more critical on this then others. But for under 20 dollars what does it hurt? Matt

Very good info on firing pin springs in Tony Boyer's book of rifle accuracy.

I learnt the hard way that heavier springs are not necessarily better. A friend of mine also proved this off the bench.

Heavier spring equals more vibrational upset despite quicker lock time.

Sometimes we overthink things.

like Matt said I tried one of Tubb's Titanium firing pins and spring, for Rem. 721 Still have it! But if it weren't for Matt I would have just ignored the big group for something else. at the time I was shooting very well and he knew it, so he asked what I changed. When I finally mentioned firing pint and spring, he told me to put the old one back in and see what happens. I was there and I still can't believe the difference!
And yes BAT changed all theres from 18# to 28# spring and heavier pin.

What to do if intentions are to replace an oldish OEM spring with something better from the aftermarket while keeping the 700’s OEM spec firing pin?

Replace it with an original spring. Wolff are my choice

I'd get good ones from Kelbly if it's a comp gun.
