Lock time for different actions

farbedoLock time for different actions
Does anybody have any data or a good feel for the lock time differences between a speed lock converted M1917 or P14, and a speed lock Interarms Mark X compared to a Remington 700, or Winchester M70?

craigsterThis might give you a rough idea:

dpcdSure, they are slower, but it don't matter in a hunter.
Here are the numbers
1917 speedlock; 3.2 ms
Issue 1917; 6.5 ms
M70 Win 3.5 ms
Rem 700 LA 3.0 ms
Rem 700 SA 2.6 ms
98 Mauser 5.2 ms
03 Springfield; varies with year; pre wars are about 5.5-6.5; wartime A3s are 7.6.

farbedoThanks guys. That is what I was looking for.
I didn't have a specific need for this info. Yesterday, I was looking at the actions that I have on hand and had them sitting on the work bench. Kind of hard not to compare them when they are sitting side by side.

ramrod340Had twin MKXs one speedloc the other normal. I sure couldn't see a difference in accuracy.
For a hunting rifle shoot what you want. Target lock time might count.
If I had a choice of normal MKX FN etc or a speedloc MKX the std wins hands down.
As usual just my $.02

GatogordoVoere (of Germany) claimed to have the fastest locktime of all commercial rifles, .006 seconds. These were later sold in the US by KDF and Kleinguether.

When considering US based operations of guides/outfitters, check and see if they are NRA members. If not, why support someone who doesn't support us? Consider spending your money elsewhere.
NEVER, EVER book a hunt with BLAIR WORLDWIDE HUNTING or JEFF BLAIR.
I have come to understand that in hunting, the goal is not the goal but the process.

speerchucker30x378In a lot of instances I have seen some bad stuff come out of speedlock systems. I have seen the titanium firing pins cause misfires. Especially when cold thickens the oil and works on the spring. I have seen threads pick up and gall in the bolt bodies and on the bolt shroud with high performance racing springs. I have seen misfires when the striker travel is reduced. I have also seen primer piercing problems with all the systems at different times.
These are of course exceptions and I see them because that's what people do when their gun doesn't work. They bring it to me. It doesn't happen to everyone. But, for the theoretical gain you could experience. Is it worth it to compromise reliability if you're going to spend a few thousand dollars, take two weeks off work, to hump your ass half way up Alaska, to take one shot at a sheep, at 200 yards?
I just have to be different and hard to get along with you understand!
When I was a kid. I had the stick. I had the rock. And I had the mud puddle. I am as adept with them today, as I was back then. Lets see today's kids say that about their IPods, IPads and XBoxes in 45 years!

AtkinsonIts a trade off, A good trigger is about all I have ever needed on a hunting or varmint rifle and even for bench rest..Lock time is OK for me with most Mausers, Winchesters, most all factory guns..Lock time stuff tends to have misfires or so it seemed to me and when it worked as advertised it didn't impress me much..
I suppose a bench rest competitive shooter would want one, but heck the trick their guns out with everything on the market or at least the newbies do..The guys that win all the money don't seem to be all that particular, go figure.

speerchucker30x378The old classic miscalculation between minute of angle and minute of Moose !

There is a reason military service rifles have heavy, robust firing pins and strikers. For those rifles a low failure rate, long service life, and the ability to fire under the worst of conditions is much more important than a few milliseconds of lock time.

It would be nice if they still made them that way. Unfortunately, when you let an engineer play with something they seem to think that even turds have to be polished to so many microns, +-.0005 inch in tolerance, ergonomically and aerodynamically designed. All this, when all you wanted was to get it from bung to ground every time, which now it doesn't do anymore.
The more you overtake the plumbing, the easier it gets to stop up the drain.

Uncle GrinchA sleeper of the fast lock times was the Rem 788. I have seen times posted as fast as 2.3 ms.

yep.. for a long time, it was the fastest production -- of course, etronix is "faster"

DeakinI beg to differ on the need for lock time on a hunting rifle. I have a very early Montana 99 LH in 260. On the bench it was Ok but several times during a hunting season I seemed to have issues with the accuracy when an animal was running.
Now I admit I can shoot well but have a tendency of coming off the stock to see what's going on. (nasty habit but working on it). I changed several scopes thinking they were my issue.
I called Montana and sure enough they had installed very sub par firing pin springs. I ordered one from Midway as Montana wouldn't send a replacement. The difference was huge. The original spring came from a Bic pen and the replacement would be compared to a spring from a Mac truck. The lock time was more consistent with Shilen trigger in my 700. This rifle is great now and it was lock time for me.

.006 Sec = 6.0mSec
Now fit that into dpcd's chart
