Lock times

Has anyone actually tested the lock times on these rifles:

Ballard

Stevens 44 1/2 or CPA

Win. High Wall

Farrow

I talking about factory issue, no shortened falls, lightened hammers o.k.

I have a suspicion that the differance is minimal.

Yes, they are slower then the Miller I once owned.

I'm casually starting some inquiries as to how my local Physics Dept might be able to help me make a test bed to measure these lock times.  Based on the actual arc of travel of the hammers, I don't expect a significantly high value for any of them nor much difference between them, but the proof will be as they say, in the pudding!

Several ways it could be done.  Sound might be the easiest.  Recording the sound (oscilloscope with storage capability and triggering) is one option.  I'd use LabVIEW (a high-end computer program in instrumentation).  With a scan rate of 100,000 scans per second (both 'scope and Labview) you should be able to quickly identify each 'event' in the motion.

The study results would make for a good article in the SSJ.

Dick, for what it's worth, Cyle and Dean Miller had the lock time on their Miller rifle tested several years ago at a university in South Dakota.  It was measured in milliseconds.  Cyle said the only action comparable (close) to the Miller in lock time is the Martini International Mark II.   

They did not test any other rifles that I'm aware of.

As you know, decreasing the hammer fall on a Ballard to 1/4" dramatically accelerates the lock time on that action.  The only downside is the half cock notch is eliminated.   

I have a Farrow rifle from Miller Arms that has an extremely short hammer fall with a stiff coil spring behind.  It is FAST!

Ballards may be weaker,
but they sure are neater!

And once we figure out how much the difference is, then we need to figure out how far one can move off target in that many milliseconds! Grin

Excellent!  (I know I can get onto the adjacent target quite readily.)

Obviously the shorter the time the more consistant one can become.

Would a short barrel be necessary to optimize a quick lock time?
Keep on hav'n fun!

greetings mikeT.

you have not been ignored. welcome to the assra board. hope you will be with us for a long time..

now for your question. yes and no.. it depends on the shooter, his stance, swing etc. some people hold a longer bbl more steady then they can a short one. while with others its the opposite. so it will help either shooter.

in theory only, a short bbl should benifit more with a faster fall. but then, why does my fbw rifle with an 1 1/4" hammer fall shoot so good(:>)..

again, welcome and ..ttfn..grampa..

Green Frog   our mutual friend Ray P. has made a striker action for the Ballard which has reduced lock time by two thirds    measurements done by equipment provided by a research physicist from Fermi labs contact me for details

If we are holding the rifle on target as the firing pin or stricker hits the primer anything that happens before that moment is not material but I would rather have a very fast locktime although it dosen't seem to help my shooting.  Some good shooters have rifles with a fast locktime and some good shooters have rifles with slow locktimes but all good shooters have something more important [IMO] good wind doping abilities.     leadball

Dick;
       Can't wait to see Old Ray's stricker action Ballard, if it shoots better than his hammer gun he will be hard to beat.   leadball
