I had a guy from Limbsaver on a hunt this past year and he brought a few of their products for me to use and try out. The X Ring de-resonator was one of them

I have a couple light rifles and thought it might be best to try it out on those as it seems the vibration might be worse in those thin barrel rifles. One is a Tikka T3 superlite in 223 and the other is my Kimber Montana 84m in 280AI

Has anybody ever used these? Some reviews are good and some are indifferent. Would love to hear y'alls thoughts

If it is the thing that looks like a doughnut, I have used them many times to dial in a load just like a BOSS works. I start at the stock and fire two. If they are not close together I move it about 1/8". Eventually you get two very close together. Fire a third. If it is not in the group move it a 1/16". That should bring it in.

Ive got one on my 270 WSM featherweight SS and it does as advertised-groups tightened up about 1/2" at 100 yds. I'd put one on my 99F, but don't want to fudge with the factory sight.

If you use it make sure you have enough oil between it and the barrel. I didn't and mine is so tight where it is it won't go any further up the barrel and I'm afraid to use any more force less I damage the rifle. Any more rifles I get with no front sight will get one too.

If my hunting rifle needed one of those things to shoot good, I'm tripping it and getting a different gun.

When I free floated the barrel of my Weatherby Ultralight in 338-06 the groups became consistent but were in the 2" or so for 5 shots with a good load. Before floating the barrel it would group some loads around 1.5" but some were 3" groups.

Not being happy with 2" five shot groups I tried the Simms "Doughnut" and it did work in reducing the group size down to more like 1.25 to 1.5" groups with good loads. It took a little experimenting with the location of the Doughnut but it worked.

Problem was I could not put up with that ugly thing on my rifle, so after working with adding a pressure point back into the rifle, and adjusting the upward pressure on the barrel, I was able to duplicate the 1.25 to 1.5" five shot groups without the doughnut.

If your light rifles and Montana need help use tip presure and save the chocolate donuts for breakfast

Sample of one out of one.

Recalcitrant 25-06 that refuses to shoot 100 grain TSXs at a respectable speed is not the least impressed with the rubber donut. Never made so much as an iota of difference in the size or pattern of groups, shot 2 inch 2 in 1 out groups throughout the testing.

I just accepted it as karma for putting something as stupid looking as a rubber donut on one of my rifles as was thankful none of the other rifles decided to go on sympathy strikes.

I'd have to agree.

I see them all the time on hunting shows (where Limbsaver is their sponsor and they get stuff free by touting it). After seeing what the guns look like, I'm happy to not use them. And I can know for sure I won't have a nice crud or rust ring on a nice blued barrel because of it.

Yuck.

About as functional as a Pet Rock...

Someone gave me a couple of them... I wasn't impressed..

just some marketing Idea at best was my impression over them..

Just curious, was he a pretty good hunter?

Just for the heck of it I tried one on my Browning BAR 7mm mag. I'm sorry to say it really tighten up my groups with it. Still looks ugly though but I have to admit it helped on this rifle.

One of my friends says it helps on a Mark X that he has. The throat is so long that he seats some of his bullets nearly a quarter inch longer than I do and he's still nowhere near the lands. He hunted with it for a while, and decided that it shot good enough groups without it.

I tried one once but didnt see any real improvement, the rifle was an MOA shooter to start with so I probly would not have seen much difference anyway........Hb

He was willing to do whatever needed to be done but we were hunting elk in December and the temps were approaching 70 and the moon was full. The animals weren't moving at all. It was a damn tough week. That being said, he was an absolute class act and I hope to get to spend time with him again in hunting camp.

Seriously, one of the nicest guys I've ever had in camp

I'd need to have some sort of powerful grudge against my rifle to put one on it.

Well, like I said, it was all free. My rifles all shoot pretty damn well but I certainly don't mind putting them on if there is any benefit. I'll try them out because he asked me to.

The slip on recoil pads are nice because I am tall and the length of pull was a little short for me. I like how they feel a little better now with those on

Drumm,
The slip-on pad is nice for increasing LOP - that's for sure.

It looks like a fume extractor on a tank barrel.

Instead of putting a Doughnut on the barrel, I suggest a Bagel.
Then you only have to Lox and load.

I used one on a Winchester 70 Classic 25-06 that didn't group like I've come to expect.
Even after removing the hot glue and bedding it properly, tried free floating the barrel and pressure in the fore-end, multiple bullets, weights and speeds.
The de-res doughnut did help but I'd lost interest in the rifle by then and sold it to a buddy who immediately removed the de-res.

Cut two inches off the barrel and recrown, should have a similar effect.

I've used one.

But not in the way it was designed to be used.

Nope. I go for the real thing.

Tracks,



Why 2"? The BOSS systems moves a couple thousandths and affects groups. If a guy had a magnum and whacked two inches he more or less turned his magnum into a normal cartridge that uses more powder and is louder.

Drumm...since I know you wont take offense, here are my real thoughts. Using the barrel donut means you'll need a T-shirt or a hat that says:

1) I don't know what Im doing
or
2) Im very new at this
or
3) Im really hoping equipment will take the place of expertise.
or
4) TYRO

At least when that doesn't work you have something to eat

The BOSS system was developed by Browning when they found many rifles being returned because of poor acccuracy were helped by cutting a bit off the barrels.
Anything that changes the harmonics will change the way it shoots.
I'd rather lose a bit of velocity than have that butt ugly BOSS on the end of my rifle and a rubber doughnut is even worse.
BTW- I love my 22" 338 WM, and don't feel like I'me giving up much.

I have used them for a few years. They work well on some rifles. And some they just move the group around on the target.

When I see one on a barrel in the used rifle rack I automatically assume the previous owner could not get thE rifle to shoot well
I pass it by every time
