15LB Hammer Springs in Ruger NM Vaquero and Federal SPP

I put some 15LB hammer springs in my Wranglers and got light primer strikes on the .22 cases.

 

Are 15LB Hammer Springs in Ruger NM Vaquero's and Federal SPP compatible ?

No,  in my experience 15lbs are gonna be to light. The 17lbs springs will work with Federal 99% of the time, but even those will still cause an occasional light hit.  The 17s will not be reliable with CCI or Winchester at all. 

 

Noticing that this is your second post regarding very light springs. FYI super light springs WILL NOT make the gun run faster so unless there is a specific reason your going so light ie hand disability etc then don't. IMO Go with 18 or 19lbs springs and you'll be lighter than factory but still reliable.

In the NMV, 17lb springs are factory.

OMV, came with 23lb.

Didn't know that, thanks

I only have OMVs.

I bought 15lb. springs from Long Hunter and have never had a problem shooting Federal Small Pistol Magnum primers. It may make a difference in whether your guns are stock or slicked up? Mine are short-stroked and still work fine. Springs are cheap, order some and give them a try.

If tuned you can get 14# springs and they work just fine in all of mine with federals, no problems. (Not 22)

You cannot say whether something is compatible or non-compatible because guns, even the same models, are different.  The NM Vaquero has a retracting pawl to aid in loading.  How well that pawl fits can make a BIG difference in what weight spring will reliably ignite a primer.  Remember the factories put in heavy springs for two reasons.  One to make sure to get reliable ignition and the second is to overcome the friction of poorly fitted parts.  Fifteen pound springs are no problem in a NMV IF the internal parts are properly fitted and tuned.

I've used 15# springs in my New Model Vaquero's for 3 years now along with a polished spring strut and deburred and smoothed internals and have had no issues using Federal small pistol primers. As mentioned above lighter springs won't make you faster, but in my case, it sure did make the arthritis in my thumb feel a whole lot better!

I have heard this before, but all the NMV springs that I have tested are 23 lb.

Wolff Gunsprings would be a good source of information on this.

Have you tested a Ruger factory OMV hammer spring?

Just wondering how you test the poundage?

Why would you even want a spring that light?  These guns have slow lock times.  Why make it worse?

 

15LB? It seems a very common poundage for Wranglers (and Vaqueros) searching the SASS forum and the websites that stock parts.

 

I'm getting on in years and my thumbs have a lot of pain in the joints, silly things in my youth are catching up to me.

I think it's one of those cases where something that really doesn't help gets a lot of attention.  You're already finding that the spring is too light to set off primers.  It's unreliable, in addition to making a slow lock time even slower.  Buck the trend.  Put in a spring that's heavy enough to reliably set off primers.  Otherwise you're chasing a problem that is really expensive to fix, and has no benefit.

Things aren't as easy to procure here as in the States. All the Aussie cowboy gunsmiths that stock aftermarket springs only stock 15LB ones, so my choice is to install 15LB springs and them build up with washers until I get 100% rimfire ignition.

Ugh.  Frankly, I'd go back to the stock springs.

Its costing me very little money and my time, both I have readily available. If I can ease cocking the hammers for my thumbs whatever amount, all very much worth it to me.

Then cut a coil off the stock spring and go to the range.  Problem is, when you go too far it's too late.

 

15 pound springs are far too light.  If you have issues with your thumbs, maybe these guns aren't right for you.

 

I have problems with a palsey.  When I use my hands they shake like a leaf in a high wind.  i can't shoot anymore.  I guess I'm getting old and don't have much patience anymore.  I have nothing left to suggest.  You're going to have to figure it out.  Good luck.

Searching I've probably (guestimating) I've read over 150+ folks using 15LB springs in their Vaqueros and looking online at aftermarket spring sellers, they nearly all to a T stock and sell 15LB springs.

 

There's no way I'm cuttin' coils off, then I can't go back.

 

Its just going to be a process. Work on them at home and go to the range and shoot them and see if they work. Don't bring them home and increase the poundage of the spring with a washer. I'm happy......it gives me something to do and something to ponder on and solve.

Oh and please excuse my manners. Very sorry to read that you're having hand troubles. These things can be very trying as we get older and still want to enjoy what gives us pleasure. I hope that you can find a workaround or some treatment.

Thanks, but there isn't any treatment for this yet other than brain surgery.  My apologies too.  I'm sitting here listening to a crap ton of explosives going off.  My dogs can't handle it.  I can't handle it.  My anxiety level is through the roof.  Good luck with your project.  I think you'll end up finding that you need to go through the hassle of ordering 19lb springs.  But that's just a guess.

Yes, 23lb. I keep Wolff 15 and 17 springs in stock and they test at their stated rates.

I have a spring weight tester. I have worked on a lot of Wranglers for shooters and 17lb. is as low as you can go and get reliable ignition.

Can you post a few pictures of this device? 

Would like to see how it works.

What .22 cases are you shooting that utilize small pistol primers?

.22 goes with the Wranglers

SPP goes with NM Vaqueros
