Anyone Use a LimbSaver Sharpshooter X-Ring Barrel Dampenerr?

dreadpirate · May 29, 2017

A rubber ring made by LimbSaver that fits around the barrel and supposedly increases accuracy by dampening barrel whip.

Looks interesting.

Never heard of the thing but the reviews do look pretty positive. Gonna follow this. It SEEMS like just abother gimmick at first glance but it seems quite a few shooters are getting improved results.

No personal experience with it, I have seen Jim Shockey use them on some of his hunting shows. Maybe just the thing too, for those older Mini 14's that everyone criticizes.

I've seen these before, but never personally used one. I know some folk spend a lot of time and effort trying to remediate inconsistency in their rifles, and improving/modifying/altering barrel harmonics seems to be a thing. 3/4-1 MOA is pretty much the best I can do with any of my rifles though, so I don't really think I am a good enough shooter to know when the issue is with the gun and not me. If I ever get to the point where I am shooting beyond the accuracy potential of any of my rifles, I would certainly look into a cheap fix such as this.

I have them on all my rifles and I think they improve my accuracy.

My Savage 10 308 has marginal accuracy ~ 2 MOA. I also have a Thompson Icon bolt gun in 243 that is pretty much an MOA gun. I am thinking the issues with the 308 are mostly due to flinching as that fly weight Savage bolt gun has a nice kick to it. I am going to try a limb saver and this Dampener. Sounds like it's hit or miss as to whether it will make a noticeable difference.

I have had the exact same issue with my Savage 308. Kicked the piss out of me the first time I took it out. Put a limbsaver on it and things improved drastically. Accuracy isn't where it needs to be but I'm still convinced it is me and not the gun right now.

If I can get something less than 1.5 MOA with the Savage 10 then I'll be happy.

Free floating the barrel and then doing 3 point bedding can sometimes do the same thing. The BOSS system works the same way. What does controlling vibration at the time of lock-up mean?

dreadpirate · May 29, 2017

I am going to try the slip-on Limbsaver. If my groups improve - I'll use the slip-on for the Mosin and get a grind to fit for the Savage. I just don't want to go the grind to fit route if it's not going to do any good.

[EDIT] I mean use the slip on recoil pad WITH the dampener. I switched context mid stream. It's what I get when I drink and post at the same time.

You got a good point there.

Here is one explanation:

OBTW - when he says 15 pounds - he is talking currency not weight!

j_h_smith · May 29, 2017

Is there a sweet spot where you will get the most accuracy improvement, or do you just slap it anywhere on your barrel? Personally, I think bedding will give you a better shooting rifle. But since I don't know enough about this device, I won't put it down as black magic yet.

Good luck to those who are going to try it.

I have gotten good results with glass bedding my Savage Model 110 in .243 and plan on doing the same to a Model 10 in .223 that I bought.
I would think that with the Limb Saver, you would have to retune it every time that you change your bullet weight, powder load or brand of ammo and maybe even lot number of factory ammo.

As for the first video:
1. Not all oscillations are standing waves.
2. Even if the barrel eventually settles down to its resonant frequency, that matters not one whit if it happens after the bullet has left the barrel. The bullet travelling down the barrel is inducing oscillations as it travels, perhaps in an asymmetric way as it traverses the distance. He assumes a resonate standing wave has already been set up both behind, and in front, of the bullet. Maybe, maybe not.

As for the second video:
It is subtly but importantly different than the first explanation. He speaks of "dampening" the oscillations. That's NOT the same thing as changing the frequency of the standing wave, which is what the first guy said in so many words when he showed the graph that doubled the number of nodes, or the location of the nodes relative to the end of the barrel. The first video dealt with frequency; the latter dealt with amplitude. Not at all the same thing.

That's NOT to say this thing does or does not work, only that these two filmmakers have not scientifically made their case (and that they disagree as to the cause). Frankly anything that alters or constrains the natural oscillation of the barrel really IS likely to alter the POI, perhaps in consistent if a priori unpredictable ways.

The real way to test this out is to get some good high speed film of the barrel being fired with this device on there at different locations on the barrel under controlled conditions. Again, not saying it doesn't work, it might, but at the moment all we have is anecdotal evidence with guesses as to the root cause. So at the moment color me convinceable but skeptical pending a real scientific analysis.

The position of the Barrel De-resonator depends on the ammo generally so you need to play with its position until you find the sweet spot. One thing they seem to be really good at is tightening up the groups of cheap ammo. I have seen tests where it reduced the group size of Federal bulk .22 LR by nearly 1/2.

Stevie Boy · May 30, 2017

The adage "if it seems too good to be true..." probably applies but, then again, it's only $8. However, how many rounds do you have to fire (and hours of time) to find that sweet spot? Is every Model 10110 the same sweet spot? My guess is "no." I'd like to hear more from thoise that have actually tried it and how the whole experience plays out.

BradMacc82 · May 30, 2017

Never felt the need to buy one, and then attempt to find that 'sweet spot' - while burning up valuable barrel life and ammunition.

DaemonAssassin · May 30, 2017

^^^^^ This.

But then again how much of it is a psychological thing too? You are told it is going to make your groups better, and boom, you shoot better! Is it the thingy or is it psychology, and some genius out there that is making a boatload of money on people that are looking for a magic cure for bad shooting?
