Cheap barrel tuner - LimbSaver Sharpshooter X-Ring Barrel Dampener

#40Fan

Today was a great day for shooting. 78° and very calm. I had bought the LimbSaver Sharpshooter X-Ring Barrel Dampener a few weeks ago, but never had the chance to try it out until today.



Savage short action.
Shilen 1:8 Select Match 6mm BR.
Fresh from the box Lapua brass.
CCI 450.
31.2 grains RE-15.
Moly coated 107 SMK, .020" off the lands.
200 yards.
5 minutes between groups while using a barrel cooler in the chamber.

Fired three shots with the Magnetospeed to warm up the barrel and get some speeds. 2878 fps.



Made a small scope adjustment and put the dampener on at 3/4" from the muzzle.





Moved to 1 1/4".





Moved to 2". Spaced out the 1/2" per step here.





Remembering the 1/2" per step, I moved to 2 1/2".





3".





3 1/2".





4".





With the last three rounds I had, I gave the 2 1/2" position again.....and I was so happy to see the first two touching, but managed to psych myself out and pulled the third shot. :(






Will test more this weekend around the 2 1/2" mark and see what happens. For $10, I am very happy.

how does it hold up to barrel temps.,,I know Limbsaver stuff takes out a lot of vibration on bows,,
 
run it through mill,,and give results,,,I could put one on my Fal and really heat it up,,
 
I bought one of those for my sporter barreled CZ 17 HMR and saw groups shrink about 25%. Nice accuracy upgrade for $9.00.

After that trip to the range I noticed a thick rubber grommet in my shop that by chance fit my heavy barrel Savage BMag 17 WSM. Despite a 1 lb trigger and bedding job this rifle has always been inaccurate. I blamed it on the ammo. I took the rifle to the range, shot a couple of foulers and then 4 shots on paper at 100 yards without the grommet for an abysmal 3" group. I then slid the grommet on and first try, Bingo! A 5 shot group that shrank more than 300%17 WSM Grommet Tuner Pic.jpg 17 WSM Grommet Tuner Groups.jpg 17 WSM Grommet Tuner Pic.jpg !! Fantastic accuracy upgrade for no $!17 WSM Grommet Tuner Groups.jpg
 
I tried one years ago and it did work, the position would change the group size. I had the best luck with it about an inch back from the muzzle. Ugly as sin but you can't deny the results.
 
Years ago, I used one on custom actioned benchrest rifle, in conjunction with one of Jackie Schmidt's early tuners for an entire weekend long event. That worn out, middle of the pack at best barrel won its last match, at 200, despite me being the shooter. It had never done that well before. It seemed to shoot truer to what the flags showed all weekend. There are three reasons that few will try one,none of which have anything at all to do with accuracy. They are ugly. They are inexpensive, and very few would exchange looks for function unless forced to do so.
 
The real question would be whether or not he would even test it, if he had not seen someone win with one.
 
Using an example, Mike created his particle dampened tuners without anyone using particle dampening previously.

On a different slant, the Bukys tuner uses a mostly conventional tuner with a runner “snubber” on it.

I tell you, if you put up some fake wood and bragging rights, there is no end to what people will do to claim them. Me included.

Jackie schmidt started that. He had some kind of bushings like that for marine driveshaft vibrations if i remember right
 
Before I rebarreled my Rem Model 7 that had a pencil thin No. 1 contour barrel I tried one. After experimenting with different position on the barrel to obtain the optimum dampening affect, the Model 7 groups reduced about 20% or so, a noticeable improvement. These can work, at least in my limited experience.
