barrel deresonator/better groups

[j_22250]

wondering if anyone has actually used one before. they have good reviews on them over at the cabelas website. anyways i have a factory gun that shoots a little under M.O.A., but i'd like it to be able to shoot at least 1/2' M.O.A.


this gun is factory, has been bedded, 3lbs. trigger and barrel is floated. didn't do complete barrel break in; cuz after i ran my metal solvent thru i only noticed trace ammounts of copper and only after 15-20 shot strings; but i did clean after every shot for the first 5. then went after every 5,10 and finally 15-20. not terrible groups 1' at 100yrds and 1-1/2' at 200yrds. jst got spoiled w/ other custom/semi-custom guns that i own. is it possible that groups will shrink with time?

I haven't used that type but I have been around a few other tuner's and they seem to work. That being said if i was looking at doing it I would go with one that threaded on the muzzle like the shade tree or something like it.

well, i've never heard of a shade tree before. are you refering to a muzzle break or something of that nature? i just figured that $18 might be worthg the money as compared to a rebarrel.

i made an 8', 11 oz dampener for my old mini 14 which took it from 5' 100yd groups to 1' with the same hand loads but the smaller the starting groups the less it will help.

If $18 will take your rifle from 1 MOA to .5 MOA, I say go for it.

 

[j_22250]

i don't know if it will or not, but after reading the reviews at cabelas and at midway, it might definatly be worth a shot.

We've tried that rubber deresonator on an .875-diam barrel 17 Mach2 and on a narrow-contour .223 Tikka. There was no discernable difference in groups positive or negative. Notably, both those rifles tended to 'toss a shot' out of a group and that tendency remained. I'm not saying it can't help, but the two times we tried it, the rubber unit didn't do anything.

Here's what i was talking about www.shadetreeea.com

I have been using the limbsaver deresonators for a few years now. It works very well on my factory 22-250. Where I shoot, if you put one on your barrel, you have to shoot in the custom class, even if you are using a sporter weight rifle!
On the average, the deresonator reduces my 22-250 groups from .6' to .35'. I have shot five shot groups in the high .1' area but only in very calm conditions.
It probably would be worth a try. The worst it could do is nothing.

that is very true. next time i place an order i might jst add one of these. if it doesnt do anything for one rifle, hell it might for another.

Here's another factory rifle that shoots in the .1's. With all of these great rifles around how can so many people be bad mouthing the firearms manufacturers? I say God Bless them.

The guys in BR using tuners need to make minute adjustments in order to 'tune' their barrel to a corresponding load and atmospheric condition.
I give their knowledge and shooting skills more credence than anecdotal experience from recreational shooters.
I just don't know how you get REPEATABLE results from a rubber thingy that just slips on the barrel.
If it was that simple to achieve accuracy, everyone at your local range would have a deresonator or a Browning with a Boss on the end of the barrel....I, for one, see very few.
The best way in achieving smaller groups is to use windflags and learn what they are telling you.

I have asked shooters what their results were with Deresonators. Some has reported significant improvement, others have not. I think that it depends on the rifle. One thing that I can tell you from personal experience is that they act as a very efficient vibration damper, at least for the frequency produced when you tap the barrel. You can easily hear the difference. One think that I see, on the two shooting boards that I frequent, is discussion without experience with a particular item, technique etc. I understand this, because I have done the same thing, but I also think that thinking or acting 'out of the box' can be a good thing.

Some time ago, Sims Vibration Laboratory gave me a couple of prototype Deresonators to test. I had called with a suggestion that they produce one with a larger ID, for varmint weight barrels, which they did. About that time I was given a barrel tuner by a Texas Benchrest shooter, Jackie Schmidt. Since I had both, I tried them together and individually on the barrel that I had had the tuner fitted to. In my limited testing, it seemed to me that the Deresonator increased the performance of the system slightly over what was obtained with the tuner alone. Later Jackie incorporated a rubber sleeve with a brass over sleeve into his tuners. I think that he believes that there is something to be gained from the damping.

One time, when I was at the Visalia range, I saw a fellow shooting a hunting rifle that had a Deresonator on the barrel. I asked him what his experience had been with it. He told me that the rifle was one that he had bought for his son, after first buying one for himself that was very accurate, out of the box. Unfortunately the second one was not. After spending a couple of hundred dollars on different bullets and powders to try to find a load that the rifle, he tried the Deresonator. The difference was spectacular. He had had to do some experimenting with position on the barrel, but I would expect that, and is suggested by the manufacturer.

I tried mine on an accurate Savage varmint rifle, I could see no difference, but then it shoots pretty well as is. A friend had the same experience, but two of his buddies saw significant improvement. I think that for a good shooting hunting rifle any improvement may be so small as to be 'lost in the noise'. On the other hand, if you have a problem, the cost is so small, why not give one a try?

Hello Boyd,
I agree with your statement that an accurate rifle shows very little or no improvement with a deresonator. I tried a Limbsaver deresonator on my 6mm BR Custom rifle and it tripled the group size!! It appears that a finely tuned rig is un-tuned by putting a deresonator on the barrel.

all good points guys. i'm gonna redirect my questioning jst a bit. has anyone ever had a factory rifle,remington in specific)that the group sizies have shrank considerably jst by putting more rounds thru bore and regular cleaning?
