light wieght firing pins

[Ggmac]

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.

Remember , he's also selling

Does anyone know the locktime of the Bighorn TL3? Also I heard it has a shorter firing pin fall. Intended to make bolt lift easier. Maybe this will breath new life into a dud (pun) thread.

After you switch to a speedlock assembly come back here and we’ll tell you how to fix your broken gun and shrink your groups by 75%!!

Dusty, Hopefully they will learn early on. I've had things similar to this in the old days and chased my tail for the rest of the season. Go to the range and shoot a lot over flags and quit reading opinions from other rookies.

Light pins, springs and low fall are KNOWN to harm accuracy! I see it constantly in my work. It bothers me when things are not vetted before being sold. Ignition issues will have you chasing your tail and spending a lot of time and money trying to figure out why you just cant get a competitive barrel.

To the OP,
As I have posted in a similar thread, I have already went down this road swapping a Rem. firing pin and spring for the HS Tubb version. The rifle went from shooting little knots to large patterns. Put the original back in and went back to shooting small again. As Mark Twain said, "you don't live long enough to make all the mistakes yourself, so try and learn from others".
I hope this helps,

Lloyd

I guess it all boils down to vibration patterns and if the firing pin strike is extremely consistent, then I suspect the rifle could be retuned back to its previous grouping ability if impact isn't excessive. I think having a firing spring system that exhausts spring energy prior to full primer indentation is probably the ultimate if inertia is sufficient to finish the job. You don't need a jackhammer-like strike upsetting the whole rifle and maybe this is where some speedlock kits come undone.

Small changes sometimes yield undesirable outcomes. Fast lock times are nice in any circumstance but aren't always necessary.

My $0.02 worth.

Lighter firing pin and 28# spring helped on that '98 Mauser. So did the Timney trigger.

That spring was probably that old that any new spring would of helped it. I replace mine every two years because vertical starts to show up. Matt

The same hold true for most any custom action. I change my Panda springs every couple years.

 

[jds holler]

I am curious to know what method of test is used to accurately time a lock to the degree of .0017 seconds. jd

 

[Alex Wheeler]

One thing I can guarantee you is a Timney trigger will NOT help your lock time. You can hear the difference with a Timney in there they have so much drag on the cocking piece.

I used my first titanium Tubb Speedlock kit way back in 1991 or so. The rifle was very accurate. The whole concept seemed to make sense. If I remember right, the way it was explained {by the cat selling it} was something like "the bullet is three feet out of the muzzle of the speedlock equipped Model 700 before the primer was hit" on the one without. The theory went on..."this allows for less time/distance for the cross hairs to move off the target before the bullet is sent" or something similar. All this doesn't come into play with a benchrest gun...I could be wrong, but it don't think it should be "moving" when you are trying to shoot it anyway.
Looking back, I never shot the rifle without it to know any different, but I believe it was just a very accurate rifle anyway. I don't know if a Speedlock kit does much for a 700, but I will say that over the years I played around with some 1903 Springfields. I dropped the striker travel from, what was it 3/4" or so, down to .250" like a 700. Got rid of that big knob and then fluted some of the strikers and installed Wolf springs. I made several of these rifles to look like a Marine sniper with a Unertl scope and they shot fantastic. None of these were bench rest guns.
They might be okay for a hunting rifle or over the course gun. It's funny, guys weigh primers, sort bullets by the ten thousandth and hundredth of a grain, count kernels of powder after weighing them and blast on faster lock time. Kind of reminds me of the people that call our president crazy also believing there is more than two genders......and he's the crazy one!!!!????
Speedlock kits....I stopped messing with them. I really believe a captive bushed firing pin makes more sense. Just worked on a Model Seven, it had a fluted firing pin from the factory. Again, senselessness.....they bother to flute the firing pin on a rifle with a 10 pound trigger and a pre-pitted junk barrel!!!

 

[boltfluter]

That is funny, that they take time to flute the firing pin. With so many obvious flaws in plain view. Good point.

Yeah, I mean, I didn't even mention the tupperware soft rubber stock!!!! And the muzzle crown that looks like a mad half drunk circus chimp cut it with a bit brace on a trampoline. What is up with these gunmakers??? I guess if we keep on buying.....
My biggest thing is that they dare to have the word "Precision" in the title of any of these guns.

Wasn't actually referring to the Timney concerning lock time. More along the lines of making a difference in trigger pull. Since I'm pretty deaf or wearing ear protection I'm not hearing all that grinding or clashing.

With a vibration transducer and a fast enough data acquisition unit and the trending software to decipher it you can see that and less

Winter time has not set in yet! Let's see, I've made a clamp for he muzzle to make a small choke. a digital trigger, electronic wind flags, and an electronic joystick rest to work with the electronic windflags and trigger. I will only need to feed a new round after ea. shot.
Speedlock and LW firing pins that need heavier springs to make them go bang?

 

[Rich S]

So if replacing springs, whats the recomended spring for a standard remington firing pin bushed to .062? Go with a stock Remington, aftermarket?

Get at least a factory weight wolff spring if not more
