Lock time

[AP2020]

So years ago, the Remington 700 was considered to have one of the fastest lock times. I have since researched more modern actions such as the Savage bolt actions that have even faster lock times.


I did a little experiment with my high speed slow motion video camera with some of my guns.

I have no idea if there is a difference in lock time between a Rem 788 and a Rem 700, but I do seem to remember the 788 as being advertised for a very fast lock time.

I do recall that too come to think of it!

Not sure what has the fastest lock time but CG rifle actions were pretty fast around 1.6 milliseconds. They use a Belleville power pack.

I just got done modifying a jig to measure lock time using an oscilloscope. It was for a gunsmith friend. He said he has found Remingtons to be fairly quick in the 2ms range (give or take). I believe he said consistency was more important than the time.

The Remington Walker trigger is the reason for the 788/700/Model 7 fast lock times. It’s the two piece trigger with connector that allows for a faster sear release, but is the reason for some of the ADs that caused problems for Remington who wouldn’t abandon the Walker trigger because as a industry fastest lock time was one of the main selling points. The most ironic aspect to the Walker trigger is that Mike Walker tried to get Remington management to allow for a redesign of his name sake trigger when after a period of production that a problem with the trigger connector was found.

The trigger connector can pivot when the trigger shoe is pulled. This allows for a relatively larger sear engagement, but relatively short trigger pull. The problem is that when the trigger is uncocked, foreign matter such dirt, unburnt gunpowder, etc. can get in between the trigger and trigger connector moving the trigger connector forward and creating a scant sear engagement when cocked.

Whether the lock-time of my action is 1 ms or 10, why would it make any difference to accuracy? Why would I move the + off the bullseye before the gun goes off?

You wouldn't but you could, and all of us that shoot will move the gun before the bullet exits the barrel. The faster the lock time the faster the bullet gets on its way.

Perhaps it won't have much effect when shooting from a high $$ rest setting atop a concrete shooting bench. What about the legions of hunters shooting from whatever position the moment requires? I don't know. I do know that as a very young man with his first rifle, a 788 Remington, it shot pretty doggone good.

It makes a difference in offhand shooting. I believe it doesn't matter as much off the bench. Matt

Machinery's Handbook, 30th edition, beginning on page 342 has information on Disc (Belleville) Springs.

I believe that the faster locktime theory has been disproven to a point. Off a bench we can get locktime down quicker than remingtons , with lighter firing pins and heavier springs. But inertia ie. heavier pins and a good locktime gives more consistant ignition which is more parmount to accuracy

For decades the 788 held the record for the fastest lock time in a production gun. May still hold the record - dunno. Remington used to advertise that the bullet has left a 788 barrel before the firing pin had dropped in other manufacturers’ rifles. And yes, it’s lock time was shorter than the 700.

I remember the 788 lock time as 1 millisecond. My memory may not be as good as the 788's lock time. Regardless, I still have three of them and they do shoot well, within some specific limitations.

I suppose that we must imagine a long lock time, say a flintlock, to see the other side of the argument.

Shoot a 1874 Sharps. Lock time is measured with a calendar.

Flinchlocks teach the importance of follow-through between the WHOOSH! and the BANG!

Yup, learn to shoot a flinter well and you can shoot anything.

Next step down, learn to shoot a revolver/pistol well and you can shoot anything.
