Thank you for your video. Watched it and purchased a bull barrel version for my CZ 455 varmint 22lr. Improvement was immediate and incredible. First 4 shots with SK ammo, same hole! Highly recommended.

Great video, we enjoyed watching and hearing what you had to say about our product. Keep up the great videos!

Richard, missing your excellent content lately and rewatching much older stuff again. Always good stuff to revisit. Wishing you a very Merry Christmas and Happy New Year. After the holidays it will be time to get back to 'work'...please.

Hi Richard, I have been using these since very close to their introduction. I was an avid Archer and having used Limbsaver products understood that they made no junk or contingency laden claims. I was very pleased with your video, straight forward and very concise. I feel your video even without graphics or demonstration is the most comprehensive offering online . I was a reloader when I started using these and decided to "explore for the sweet spot using factory ammo. I know, I know, apples and oranges. What I found once the factory ammo led me to its own sweet spot was amazing in and of itself, but the trials with the reloaded ammo with just minor adjustment to the de resonator were more than I had hoped for. Using my personally tweaked 30.06 Remington 700 I was able to go out to 250 yards before my groups were no longer 1 hole examples. Again thank you for the very personally redeeming article. liked and subbed.

Thanks for this video. I had thought these were a bit of a gimmick, but after listening to your opinion, I put one on my rifle. I tried varying it over about 4 inches before I decided I was happy enough. I've never been able to achieve 1/2 MOA on any of my rifles before.

Very interesting, and very well presented. I have two of these on order and am really looking forward to playing with them. Didn't know about diff sizes, so I'll fit these two to whichever sized barrel.......then, once a believer........get them for all my rifles.

Cheers its going be my 1st upgrade on my 1st rifle .22lr and a 30,06 thank you

Hello Richard, I am very glad you took the time to find a way to explain barrel whip, harmonics, and the effects that reloading, the addition of the Deresonator, and how this can all provide dramatic results at a reasonable cost. I have used these for years and have withstood the laughs and snarky comments, that always seem to result in red faces and a swift about face exit when the nay sayers see the results. I bought a used Rem700 BDL in 30.06 and after doing eveything I could do to reduce group size and get consistency I would then "install" the black magic donut, and usually through patience, and documentation was able to at least half the best groups that I had previously shot without it. Now mind this, I was using only collet dyes on fire formed brass, neck trimming, weighing everything. and the greatest single advancement in accuracy was the properly determined positioning of this wonderful tuner. It has shut the mouths of many scoffers at the range when they observed the Rem 700 consistently shoot clover leaf shaped 3 shot 1 hole groups at 250 yds. So yes Richard, I am appreciating your post, knowing that many shooters with prohibitivley priced rifles have tried it, found it to work great, and never mentioned it to wifey, of the friends that used to ridicule his buying a custom rifle for an amount close to a fine holiday, or a fine Rolex! Best Regards Phil

I put one of these on my ruger american .243 and yes it does help. I followed the limb saver instructions and it helped noticeably so I have not moved it around.

Excellent video! I have ordered on of these. Thank you.

We used “tunners” to eliminate parasitic harmonics in an unrelated industry. It was more of an art than science to figure out where to position tunners. Curious how you are measuring the frequency and the sub harmonics of the whipping action of the barrel. Or are you looking at the reduction of the standard deviation of the shot placements to determined that your barrel has been tuned? Very interesting video. Richard you are out there swimming alone in the deep end of the pool surrounded by sharks. (Translated to no one else is covering this topic nor are they brave enough to talk intelligently about it). Very nicely done!

I have a 17 wsm Bmag I just bought. I put 40 rnds thought it without the tuner and I was getting 1/2" groups at 50 yards with maybe 2 of 10 outside of the group. Not bad figured it was the ammo or maybe the new barrel. I paid 9.00 for a Limbsaver Sharpshooter X-ring and went to the range. I was amazed I put 7 shots in the same hole. I don't think I have ever done that with any gun before. No fliers it was like my gun turned into a laser gun. I measure the group and no kidding it was 0.10" group of 7 shots. That was probably from me moving on the bench. I am still in disbelief. I was going to bed my stock but I don't think I want to change a thing now.

Thank you Richard for such a clear explanation. I thought they were just something to add a few oz of weight to a light barrel, and thereby dampen vibrations. But that they act like a Browning Boss tuning system and similar expensive options(that have to go on the end of the barrel, without adding to the length of the barrel, never occurred to me. Since all my rifles have moderators, and since I don't reload, this info about tuning for a factory load(if it is anyway good at all) is just too good to ignore.

Thanks Richard for your video. I was interested in the deresonator but unsure about even trying it. After watching your video I decided it was worth a try. Depending on position groups I shot varied from shotgun patterns to practically cutting out the bullseye. 👍

Yeh I was thinking a small sharpie mark,think I will give one ago,all the best look forward to the next vid cheers

This is why i love you tube left this video at 2.10 after you said the two ends of a whip hit together and spent the best part of an hour watching whip cracking (Adam Winrich is awesome at it ) then come back to finish watching your video.

these do work and work very well. i have them on 2 of my rifles. it makes the most dramatic difference on my 17HMR.

13 minutes in and I had to pause and comment. Excellent video as well as dialogue. Your explanation of this device as well as the way it works is second to none. Our UK brethren have a grasp on the English language that we here in the US have yet to follow.

I found the Mrs rubber pleasure device and drilled a hole in it, works a treat at the range and is a great talking point.

Awesome video and they do work big time.

Well said and good advice!!

Great video! I bought a 17 cal wsm rim fire which is factory only ammo. They can shoot great or poorly out of the box. So many people will spend time and money on rebedding the action/barrel fooling with action screw tension etc and still scratch head when the gun does not shoot good. I took this $6.00 tuner (cheaper on Amazon) and was able to make .25" groups at 100 yards from a .17 wsm. I did not waste time bedding the barrel etc. Mine shoots better than 17 wsm costing 3x more. I think the reason most people don't use them is they don't like the looks. bedding to get more accuracy is just hoping that the bedding changes the harmonics in a way to shoot better. Bedding can also make it worse just like moving the barre tuner to a wrong location it can hurt accuracy.

Thank you for this great video. Just brought one to try on my .22magnum. Every rimfire gun owner should try one to better their accuracy on different rounds that dont work

It's useful particularly if you have a very hot load - high velocity with a great bullet - that is a long-reach hunting load, but which doesn't group well, you can make it group well - adjusting the gun to the load, instead of vice versa.

Excellent explanation ~ many thanks

Hi! good information and accurate descriptions... I do have a question though....I have seen bench shooters during load developement sprinkle a liberal amount of say talcum powder on top of the barrel. When they shoot a round they examine the barrel after the shot to help pinpoint the nodes and place the x-ring resonator between them for best dampening....You still may need to play a bit forward or back but they claim this works well on barrels with proper load development already done .... Have you done this or something similar, and what results did you personally get after trying this method? I know I am long-winded here but I wanted you to see a better description of the process.... Thanks

I have wondered some time that can you effect the barrel harmonics without changing the barrel or messing with the bedding. Thanks for the video

Ok,,, doing some research,,, this thing actually works by adjusting the frequency wave node location. The closer the wave node is to the tip of the muzzle or end of the barrel, the less movement or whip the tip will have as the projectile leaves the barrel. AR15 users for DMR weapons can use this starting at about an inch and a half from the end of the barrel and adjust your deresonator from there to tune accordingly. Rifles start about an inch or two from the stock. Good video richard,,,

I am a huge fan of your videos. You have taught me lots of things. I rely on your info for many things because you make sense. I am waiting for my IOR Crusader that you helped me decide on. I reload also. If everything is as tight as you can get using powder charge, head space, twist rate, bullet weight etc., will the limbsaver help fine tune it even further? .1 or .2 MOA?

Hi Richard, after watching this video I put the barrel tuner on my rifle and it made a huge difference, not bug holing yet but now I am developing another load for the rifle and I was wondering what you would do starting with a new load? Would you take the tuner off and shoot initial rounds without it and find the best group out of the different charged loads and then take the tightest grouped load and shoot again with the tuner? Or should I maybe just move it back to the start next to the stock on the Ruger M77 MKII and shoot the trial loads with it there. 3/4 from the end of the stock helped greatly with the last loads. Would I assume that placement would be useful for other trial loads? Any advice you have would be appreciated. Thanks for the great video.

Very interesting. Does the influence of that "15 pounds" of rubber increases with slower moving bullets? Will it be more effective on, let's say, a 30-30 ( maybe a bad example since most rifles chambered for 30-30 have tubular magazines...but I'm using it because it's a rather slow bullet) than on a 204R or 220S?

I do have it on 2 of my rifles and I love it

After 15 years on pistols(encore) and rifles I know it works.is very sensitive and effective

Hi guys I've been looking and trying to find this tuner in the UK . I do a little bit of archery I know LimbSaver do a lot of archery equipment and so I have found , what I believe is to be the exact product made by LimbSaver but for bows and a lot cheaper couple of shops are doing them for £6.99 it's called target stabilizer you find it in the vibration dampener section in the archery shops also in different colours hope this helps oh yes different sizes !

Fascinating video! I've seen this done with electrical grommits on .22's. Can you put a link up for where you can get these mate?

I do reload. my problem is I have a 16" 308 and loose velocity with my setup. will I be able to load max velocity with no pressure signs and then tune my groups. . .

Once you find the sweet spot how do you make sure it doesn't move especially while hunting? I have a weatherby Vanguard 2 sporter in 7mm08 that shoots quite horribly with the 24" super light sporter barrel. I tried free floating it and it helped a little, but it still shoots 2" groups or bigger. I have also tried many different loads with a few different bullets with no luck. Do you think one of these may help me?

Hi Richard av hunted high and low for the LimbSaver Sharpshooter X-Ring Barrel Dampener cant find it anywere in uk online and the ones i have found on ebay and amazon wont deliver to uk any help in finding a couple would be great thanks derek

Really interesting, I had been wondering what you use those rubber things for. I saw you had one on your t bolt. I have one in .22.

+Richard Utting I am so impressed by this video and they way you explain things, I really enjoyed it. I shoot a lot of 22LR mostly from modified10/22s. Used in the correct way would this be helpful in reducing my groups? I noticed you are running a "moderator" in conjunction with your de-resonator and I was wondering the reason and if you had better results with it? I always read about suppressors negatively affecting or changing your POA/POI but I guess that wouldn't matter if you always shot with it on. I have a very lightweight aluminum SilencerCo Warlock 22, a pistol caliber SilencerCo .45 OctaneHD, and a centerfire SilencerCo Omega .308, as far as harmonics go which one would you recommend using for rimfire? Thank you!

Thanks for sharing!

And will the effectiveness increase/decrease in relation to the twist rate of the barrell?

I assumed that they were silly things only sold in the back of enthusiast magazines along with 'full auto' triggers and ED pills. Ruger put their own strange device on the Mini-14 when they re-engineered it a few years back. It went on their target model (which isn't expected to perform to your level) and I always wondered if and how it worked. Now I know!

I had a Browning with a BOSS system and that thing would shoot .1's at 100 when I had it tuned. Unbeliveable.

It definatly works. I am buying more for my other rifles. Now I do not have wait to get all reloading stuff to get good accuracy. now I get ragged holes out of factory ammo.

look into Browning boss tuner I got one ,works on same principle

Where did you get this from I would love to know

Will this limb saver work on an air-rifle? I guess not on one of those "kicking like a mule" guns...but on a finely tuned, smooth shooting one? Or even better, on a PCP? It would be a solution for one of THE MAIN issues of a pellet rifle...wouldn't it. Maybe it could work...if the piece of rubber isn't just 15 pounds in money but also in weight 🤓

I see you are enthusiastic Richard. So here are some other details. Back in the Day when I was making Anti- Blast muzzle brakes (around 1991) I sent one to Browning in America. After a 45 minute conversation with (nameless) I told him how I had experimented with recoil and brake harmonics.Basically the brake pulls the barrel into tension , initially via compressed air travelling ahead of the bullet! This stiffening of the barrel reduces the amplitude of the harmonic shockwaves travelling up to the muzzle from the breach. (actually several times faster than the bullet!) If the crest of that wave can be reduced by making it have to do some work then the vibration amplitude can be reduced and permit a tighter "elipse" of bullet exit. The energy is actually a quadratic as it has velocity squared in its solution.Thus we get two solutions one positive and one negative. So this simply means that the bullet can "sway either side of a certain number value. So it might hit half an inch high and right ,or it could strike half an inch low and left. Better damping can obviously reduce this effect producing tighter groups.The company initially was interested then six months later they were not. Three years later the BOSS system arrived. This is the plight of the inventor and big business.Maybe it was parallel thinking ? Who knows.Liverpool University tested my brake and it gave 60% recoil reduction and 84% energy reduction with a .30 caliber rifle loaded with 150 grain bullets at 3150 fps. Hope this helps a bit. Cheers! Rod Mac

Incredible education. Thank you.

Do you have to re tune between different batches of factory ammo ?

Luckily all my barrels are all to short to fit one as im still catching up with your recommended buys :D Meopta ZD 6-24 next and maybe Quick load

where can I get one in the UK??

Hi Richard, thanks for sharing your experience with the de-resonator. I just have one question. After you find a "sweet spot" with one type of ammo., does the accuracy change when you switch to a different ammo? I figure that different ammo would change the harmonics of the barrel thereby causing a change in accuracy and point of impact. Your answer will be appreciated, Thanks.

Hi Richard will these work with a fully suppressed barrel as I have a carbon wrapped tension barrel on my Ruger 10/22 & want to get the accuracy better thanks for the explanation I have ordered one now I know what they are for cheers mate

Why did the Browning Boss system disappear? Did you ever try or use it?

Good information on the De-Resonators ! Ordered both sizes last night directly from Limbsaver.

where did you get yours from?

Hi Richard. Was wondering what load development process should one use to included one of these things in the load development cycle to deaden the recoil?

What effect if any would something like this have on an air rifle. either springer, igt or pcp?

I know this might be off topic, but I really like your reviews on scopes, they are very thorough. That"s why I subscribed!

Does this work on a pcp airgun?

Have you got any experience with the device made by browning- it is call boss

Surely all that is really happening here is the reduction of muzzle lift? Moving the weight along will just reduce the lift and sweet spots will be found depending on ammunition used and distance to target.

does anyone have a link to buy one of these? cant find them anywhere!

Great video man! Do you need the barrel tuner if you are using a suppressor/silencer???

Been using them for awhile now. Limb Saver products just simply work.

Great video Richard. I'm going to give a couple of these a shot. One on my .22LR and one on my .308. A couple of things though... 1) It appears that the LImbsaver instructions recommend moving the tuner/dampener by 1/4" at a time (approx.6mm) but you mentioned that a 1mm change can have an effect. What increments do you suggest, especially when close to identifying the "node"? 2) What are your thoughts on doing this at greater distances, similar to how folks do ladder testing at 300, 600, or 1000 depending on their goals? Thanks Jeremy

Does anyone have a video that shows targets that have been shot using a rifle without a barrel tuner and then targets that have been shot using the same rifle and same ammo with a barrel tuner. Would be a lot easier to "see" the difference.

I got half an inch with this and got it out to 800 yards bang on pice a cake

HELP! Is there anywhere in the UK that sells these? I must have tried at least 20 places and 99% of them have never heard of a barrel tuner. Any help would be much appreciated.

That cost 15 pounds! Geez. I got mine for $8. Nice gun though. And great explanation.

So, basically I could do the same by varying the powder load of my ammo?

im going to try this on my air rifle. what are the chances if would effect an air rifle to the good, i wonder?

Hell yes they work...Browning has had their BOSS system for decades.

Unless you can fix the tuner to the barrel, surely every shot it moves I'm having one made by an RFD (about £80), which clamps to the barrel with an Allen key after you've adjusted to improve your group.

ok im not saying it doesn't work . but I believe less is more . the last thing I want is one more THING on my rig . so question . - how many rounds down range to find the sweet spot ? - and could you not accomplish the same thing by conducting proper ladder testing im sub half moa without one

....I thought they worked equally well with factory ammo as well as reloads? Even the best reload creates a harmonic wave down the barrel that benefits from having the deresonator in the right place to reduce the effect of the wave on the bullet?

Going to cut one, wire it onto my mini 14 with the other stabilizer . I’ll report back

where can I get one

15 pound piece of rubber!! WOW! that's heavy.... Or maybe I'm getting the U.K. Mixed up with the LB.

couldn't One simply wrap a coil of lead solder around the barrel, and slowly try moving it along the length of the barrel, to find the "sweet spot"?!...

Well, they are ugly, BUT: I had an eye opening experience yesterday. Since a while I´m struggling with my Tikka T3x CTR in 6.5 CM and a 24" barrel. The barrel dia isn´t really big for that barrel length, and I loaded 8 different bullets in several loads, including 3 different powders and so on. The very best groups where at barely .5 MOA, which isn´t bad at all for a factory rifle (which I bedded), but doesn´t satisfy me for LR shooting. And I know some Tikkas with shorter barrels which all do better. So yesterday I was out for V0 tests with my new bought Magneto Speed mounted at the barrel mouth. Guess what: The first load I shot gained tighter groups than ever, and so did the two others. I couldn´t believe it, all of them were under .5 MOA, one of them was .3 MOA, which would be all I want. Should I let the Magneto mounted now forever? So I searched around and found this video - thanks Richard. :o ) Might be a big step forward for me, but I said it once, this dampener is really ugly. Does somebody know other damper models, which are a bit more charming on a rifle barrel? If so, I will think of you in my prayers. Cheers from Germany.

Interesting info, and I do understand the concept. But, by the time you've found your ideal powder & load + seating depth to get good groups, then stick a moderator on the end of the barrel upsetting everything, so have to start again. Then, just when everything eventually settles down, you stick a tuner on it. Bugger it, off we go again! By this time you've spent a ton of money on the consumables, days if not weeks at the range, your wife has left you, you've a few more grey hairs, people have started to notice that you talk to yourself a lot.....and your barrel is starting to wear out, fit another one and start all over again from scratch. I don't want to be negative, but life's just to short.

Why has someone put a dislike , invaluable

This is why everything being equal, a heaver rifle will shoot better than a light one.

On a working gun that gets dragged in and out of cars, over gates, and through hedges, I would be concerned that it would get knocked out of position.

Do they work on floating barrels as well ?

Why don't you start with a heavier barrel and get rid of that fluted one for a stiffer barrel to start with? I've seen alot of bench rest shooters punch the same holes at 100'. Their rifles didn't have any bullshit hanging on their rifle. They just just a quality barrel, handloads and trigger and a very heavy rifle overall.

Harmonic balance

You can get them from artery shops they are made by the same company call target stabilises you can find them in the vibration dampener section and they are cheap come in different colours

Hi, if you use Border Barrel, you should read the article on an experiment made by this company about "positive compensation" by Geoffrey Kolbe : www.geoffrey-kolbe.com/articles/rimfire_accuracy/tuning_a_barrel.htm

I think my 7mm mag could use one of them.

Full bed the action n reload 👌

All I know is you can tune a piano, but you cant tune a fish.lol

My phone is being a twat apologies for a million posts

Surely that thing doesn't weigh 15 pounds. It's much too small. Does he mean 15 ounces?

but its so uggglyyyyy
