Do anyone have lock time numbers on any rifles?

(What is lock time? Look at bottom of post)

Does anyone have numbers of lock time of various rifles? I'm trying to create a more complete list

What I found so far (I cannot verify, I find it strange Tikka T3 is this fast for example)

Rifle Model	Time in Millisecond	W/Speed lock
Tikka T3	1.3
Anschutz 2000	1.5
Remington 700 TI	1.6
Savage 116	1.65
Anschutz 1800	1.7
Anschutz 1400	2.3
Remington 700 SA	2.6
Winchester M70 SA	2.6 (-40%)
Remington 700 LA	3	-40%
Winchester M70 LA	3 (-31%)	-31%
Ruger M77	3.4
Mauser 98	4 to 5	-40%
Springfield 1903	4 to 5	-40%
Enfield 1917	4 to 5

Manufacturer and Model	Lock Time (milliseconds)
Rößler Titan 3, 6, 16 and Alpha	1.6
Savage 10 AccuTrigger	1.6
Anschütz 1827 Fortner	1.7
Sig Sauer 200 STR	2.4
Remington 700 (short action)	2.6
Winchester Model 70	3
Remington 700 (long action)	3 to 3.2
Ruger M77	3.6
M1917 Enfield	4 to 5
Mauser M98	4 to 5
M1903A Springfield	5.7 to 6.5
Lee–Enfield	8 to 9
AR-15/M4/HK416	approximately 10

What is lock time?
Lock time or action time refers to the time interval (often measured in milliseconds) from when the trigger of a firearm is activated until the firing pin strikes the primer, and depends on the design of the firing mechanism. A long lock time increases the probability of the shooter pulling the sights away from the target before the bullet has left the barrel, a common shooter error which can lead to poor hits or even misses.

Interesting topic

Reminds me of the Remington 700 EtronX from the early 2000's (?)
No firing pin or traditional mechanical trigger.
Specialized ammo, Ignited by a electronic circuit powered by a 9V battery
From a Popular Mechanics published Dec 6 2004
"Lock time for the electronic firing circuit is slashed to 27 microseconds. That's a 99 percent reduction compared to the standard 700's."
27 microseconds = 0.027 milliseconds

No sear, mainspring, or firing pin also reportedly reduced harmonic vibration and micro barrel movements.

I have never seen one. Anyone have any experience?

There's no way to keep the sample sterile. A change in lube, rust, spring set, depth of a roll pin, trigger clearance.....literally a zillion inputs to measure.

Why do engines kiss one valve and not every valve at the magic rpm?......because of the above.

Harold Vaughn's book, rifle accuracy facts covers so much about these metrics that it will give you a headache.

Why does it matter?

It's more of a deep dive. Competitive shooters claim there's a difference, hence "NE Herd Bull" mention about electric firing circuit. Wikipedia says this "A long lock time increases the probability of the shooter pulling the sights away from the target before the bullet has left the barrel, a common shooter error which can lead to poor hits or even misses."

You can get better lock times using SpeedLock kit for many of the popular offerings of American rifles. They give an example here:

Remington 700 short-action

Standard Firing pin​

• Firing pin weight 650 grains
• Lock time 2.6 milliseconds

SpeedLock Systems pin​

• Firing pin weight 285 grains
• Lock time 1.6 milliseconds

SpeedLock Systems pin — net effect​

• 365 grain reduction in firing pin weight — 58% reduction
• • Lock time was reduced 1.01 milliseconds — 39% reduction

It’s an exaggerated example but if you want to see the effect of lock time try shooting a flint lock.

I tried some of those speed lock systems before and they wouldn’t light off my primers. Went back to factory and had zero misfires. I only buy steel firing pins anymore.

 

[WeiserBucks]

I don't have anything to back it up, but I researched light firing pins for reduced lock time years ago. My research concluded that heavier firing pins were preferable for reliable ignition.

W/Speed lock
Tikka T3	1.3
Anschutz 2000	1.5
Remington 700 TI	1.6
Savage 116	1.65
Anschutz 1800	1.7
Anschutz 1400	2.3
Remington 700 SA	2.6

Rokslide response: "Says right here, tikka is twice as good as a M700 SA"

One of the most popular benchrest actions is a Bat and it seems most people find their design to have a design very close to ideal - this is off their information page:

 

[TaperPin]

If a super light firing pin and super fast lock time was a benefit to accuracy I’d expect Bat and other benchrest actions would simply design their firing pins that way. Somewhere it seems there was a discussion about this, and the lock time more or less reflects what’s been shown to be ideal through testing of a lot of benchrest shooters.

Maybe rifles for field shooting do benefit from shorter time since they aren’t held as steady? Idk.

I'd say that sounds reasonable. It's what happened when you pull the trigger and right after that, if you flinch, do a bad trigger pull, ect, will have more consequences the longer the bullet is in the barrel.

Also when shooting at a target on the move, say driven hunt on wild boar, I'd think shorter lock time be benefitial.

I've also read that rifles with a cocking mechanism has longer lock times then those with bolt and pin.
