40X Rimfire 'lock time' question...

Does anyone have any documented 'lock times' for the 40X (Rimfire) action as they came from Remington? I'm aware that the M700 Long Action (CF) was ~ 2.9ms, and the M700 SA was ~ 2.6ms.

Would the 'lock times' for the Rimfire 40X/XB varients be similar to the M700 SA (CF) ???

Thanks in advance...

Art, I guess I didn't understand your post On Rimfire Central. Are you writing an article or just wanting to know. I think it is 2.7.
 
I read once in I believe Stuart Otteson"s Book "Benchrest Actions and Triggers" (I believe that is the name of the book), that the lock time of a 40x centerfire was 3 miliseconds, but it doesn't say anything about the rimfires that I can remember, but that was a while back (Jewell triggers weren't even out yet).

Hi Butch,

There are several reasons, but mainly documentation on the Rem. CS 40X Rimfire action. What I've found out to date is like you said on RFC the 40X (722/40X Rimfire) 'lock times' is ~ 2.6ms from the Remington factory.

Dan - you're correct in that the 40X CF (long action) is ~ 2.9ms with the SA being ~ 2.6ms.

Again, just hoping someone has some documentation stating conclusively what the 40X Rimfire lock times are. If not, I'll go with the 2.6ms for these rifles.

Thanks guys!

Yeah I know it doesn't I was pointing out how old the book was. I never said it did.Locktime has to do with the time it takes the firing pin to hit the primer after the trigger is pulled You just assumed something that wasn't there Butch.
 
Art--I noticed the Killough Sports list the new 10X-III action made here in Dubois Pa as 2.1 ms. Also Jerry Stiller makes a real good 40x clone (Lonestar), perhaps he would know the locktime on the Rem 40x.
 
Thanks again for the tips on KSS and Jerry Stiller! I'll follow through on them...

I appreciate your input gentlemen!

I do believe that trigger design affects lock time. The time it takes the sear to get out of the way of the firing pin assembly. Might be minor, might be significant. My engineer brain stirring up trouble again.
