Limbsaver Barrel De-Resonator worth it?

[Karbon]

Anyone have a feel for these?
Worth it or not?
I'm just wondering if I should throw it on my floated barrel...

From their site...


LimbSaver™ Barrel De-Resonator


The New LimbSaver® Barrel De-Resonator is designed to dampen out unwanted vibration by shortening the overall settling time of the barrel. The accuracy benefit is immediate, providing sub-minute angle groups with over-the-counter factory ammunition. This easy-to-install unit simply slips over most standard barrels. Designed and manufactured with our proprietary NAVCOM® (Noise and Vibration Control Material), and engineered for optimum performance utilizing Sims Vibration Laboratory’s DTMS (Decay Time Modification System). If you are looking for performance & accuracy, trust LimbSaver®, the makers of “Products That Work!”™

The one non-scientific test I saw done of the device was not favorable - group sizes did NOT go down but in fact went up by some measure. The test did not attempt to 'tune' the device to find a spot on the barrel when it might work, include control groups, multiple samples, etc. - thats why I call it 'unscientific'.

But that one informal test did appear to show that it wasn't worth the effort.

If the test didn't attempt to tune the barrel with it what exactly did the use it for?? Isn't that the point of the device?

Just a few assumptions

My first reaction would be, "For 12 bucks, why not?" Try cheaperthandirt for the deal.


My second thought would be skepticism. As I am to understand it (and my understanding is rudimentary indeed) the barrel "whips" slightly as a bullet passes through it. The ways to accurize a barrel are to either make it whip consistently (a la cryogenic treatment) or make it whip less (bull barrel). The damper is obviously friction-fit, so IMHO it will either be a royal pain to put on, or it will work its way up or down your barrel. Plus it's ugly and adds weight, but if it's a match gun it doesn't really have to be beautiful, or light, does it?

A quick browse through any pistol holster thread will reveal that all of us have spent more on less (some of us more than a few times ). So I'll stick with, for 12 bucks, why not?


If I knew you from any other shmoe on the internet I'd be inclined to mail you 6 bucks and split testing time with it 50/50.

M, I, C,... K, E, Y,... M,o,U,s,E!!!

On second thought it will make your rifle even more deadly... the deer will see it and laff themselfs to death!

"Worth it"? Only you can decide. But not with my $12. To my mind, this falls into the same category as deer whistles and herbal male enhancements and other such things.

As far as I can tell, in order to dampen vibration the deresonator would either have to have a significant contact patch with the barrel (which it doesn't) or add significant mass to the barrel (which it doesn't) or significantly resist the barrel's movement (which it can't). All it can do is add a minor amount of mass and (thru it's small contact patch) try to absorb some miniscule amount of primary harmonics and release them as lower-amplitude harmonics.

Experimenting with adding pressure to the rifle's forearm is probably a lot more effective and a lot cheaper (free).

Just my opinion.

I read the same little blurb in a Midway catalogue and figured that it would require lots of fussy tuning to get it to work properly and that each rifle would react differently. I also figured that it's kind of like a lucky feather, sometimes just believing you have an edge IS and edge.

I guess this would work the same way as the Browing BOSS system did and the same as the tuners used by benchrest shooters. But those devices allow adjustments of just the smallest fractions of an inch to 'tune' the system for best accuracy. How one would really do this by sliding the Limbsaver device up and down the barrel by random amounts is beyond me. If you actually got lucky and got it tuned, any slightest bump or rub could them move the device, making it totally out of tune again. It is purely a gimic. The theoy is sound (ask the benchrest guys), but the execution stinks.

These are the exact responses i would have guessed out of this group. When I was buying my rifle a guy at Sportsman's Warehouse was pushing the effectiveness of them. He was almost irratated that I didn't agree with him or buy one on the spot. I even asked him if he worked for Limbsaver, he only responded "I wish I was that lucky, but I KNOW they work"

So that's why I had to ask the group here.

Prove it!

When someone says something like

"I wish I was that lucky, but I KNOW they work"

the correct response is, "Show me your data." Lots of people "know" things they can't demonstrate. Doesn't mean you should put your money where their mouth is. A salesman in a store is always suspect on something like this. He may well have a $$ interest in having you buy more stuff.

Back when I was in retail, the mere fact that I was NOT on comission was a selling point!

It wasn't even an employee, it was some random Joe looking at the Remington 700's.

Spend the money on ammunition.

Best "limb saver" I ever bought was the shooters friend recoil pad for $17. If anything the difference in felt recoil on a big rifle helps accuracy more than this barrel thing.
