light wieght firing pins

[6xcshooter]

Just got a light weight firing pin from gre-tan rifles. it works great. highly recommend it for anyone wanting to reduce the lock time of your remington 700 or clone action. gre-tan is now making these firing pins, comes with new spring. he also makes light weight bolt shrouds too.

Gre-Tan has done a few jobs for me over the years. I was always very happy with his work.

There are more important issues than an aluminum shanked firing pin that will break if dry fired.

The above mentioned issue only takes a few minutes(& won't break)to correct.

I once bought a titanium firing pin for my AR-15 based Match Rifle. The tip broke after a while and I went back to steel. Can't say that I noticed any difference in my scores or my X-count. What I'd like to know is whether anyone has measured the lock time with a lightweight pin versus a standard firing pin in the same gun. Pretty straightforward experiment to do IF you can measure lock time accurately. I suspect that the manufacturers of those "lightweight" firing pins don't want to see that data...

7075 aluminum shank with a heat-treated stainless steel pin decreases lock times by 36-38% compared to standard, steel firing pin. Doubtful it will break dry firing.

There is 3 points to consider in locktime reduction;
-Mass in motion.
-Spring force
-FP travel.

Reducing one need increasing the other to maintain sufficient impact energy..The mpst determining is reducing the travel, thus compelling to increase the spring force (or reducing FP tip diameter).

Reducing FP tio diameter from.080 to .065 needing also some 33% less energy allow to reduce mass in mption.

Bushing and reduction of FP duameter is quite easy, reducing travel is a, pther question.

I have seen The lightweight pin and springs make vertical at longrange shooting. Made guns capable of shooting 4 inch 10 shot groups open up to 8 inches or more. This wasn't just one gun either. Go to the 6BR forum and read the thread on Remington primer or firing pin. Matt

And as related by Glen D. Zediker in his book, "The Competitve AR15", page 52: "Don't use titanium. It burns. One blown primer center and you now have a very expensive, very light weight pin punch".

All his words, not mine.

Interesting, I'll read it. On paper I can't see how that is possible. GreTan told me that there have been a few of his lightweight pins break from dryfiring. He said that it was very few, but did recommend using a snap cartridge when dry firing.

Lock time with the factory Remington pin is ~1.7 mils (0.0017 seconds) If you reduce that to 0.0011 mils, what will that itty bitty 0.0006 of a second get you - absolutely nothing.

People will spend money for anything that has the sound of magic.

Agreed, I added a weight to the firing pin on my BAT. It shoots better. Too much BS on the forums sometime.

 

[lloydx2]

Lots of stuff to consider. Primer type, headspace, spring weight, tip diameter and so on
Some of it bullshit some not. I could see were someone using (light) pin with 22 lb spring
could have trouble with wolf primers. I have run both of gregs pins for about 20 years. The aluminum
shaft pins do have minimal service life 5-6k dry firing or not. Then they break. Thats not bullshit

Just because the primer fires doesn't mean it is consistent. The gun I was talking about was a 80 pound heavy gun on rails shot off a bench. They were all 1000 yard benchrest rigs that did it. A lot of guys are getting tungsten added to there firing pins for weight and consistent fire control. These are the 100 and 200 yard benchrest guys. Fire control is very important. Matt

Matt,
It hasn't made me a match winner, but the tungsten weight helped me.

6xcshooter,
Since it's your first rodeo,it's apparent that you'll have to learn the hard way.

 

[butchlambert]

New guy Dan!

 

[6xcshooter]

ok, I'll see how it turns out. 1st rodeo? ya think? yeeeee hawww buckaroo

 

[Eddie Harren]

Published, posted match reports, with real names, would do a lot to clear the air.

I am the poster on the 6BR sub forum who was having a problem with Remington 7 1/2 primers failing to ignite after I installed a Speed Lock firing pin assy in a Remington 700 action. The actual number was three out of 120 rounds. I am going out to the range tomorrow to do some load development with the original firing pin reinstalled and will report on the results.

I remember reading David Tubb commenting on his Speedlock assembly’s performance: He said that the difference is that the stock Rem700 FP will just be making contact with the primer, at the same time the bullet will be exiting the muzzle of a Speedlock equipped rifle. If true, that seems substantial.
