This review is about the Limbsaver Bull Barrel Deresonator (Barrel Tuner) also known as LimbSaver Sharpshooter X-Ring Barrel Dampener. I purchased it through Amazon Prime for under $8. However, you can only get the free shipping if you add it on to your order with something else. Here is the link.https://www.amazon.com/gp/product/B000KOWE82/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I own an older Anschutz Model 64 Target model which I purchased with my allowance back in 1970. So the gun is 47 years old, I was 12 years old when I bought it. I shot competition with it from 12 to 14 years old. Back then I only shot Remington green box standard velocity out of the gun. All competition was shot at 50 feet in prone, sitting, kneeling and standing. After around 16 the gun was put away and I did not shoot it again until I moved here (Oahu) 7 years ago. After having to fix a warped stock, replacing the Olympic sights with a cheap scope I started trying to test the gun with every brand and type of .22 ammo I could find on the island. While I found some ammo that would group well, I would get flyers every few rounds. The flyers would open up 50 yard groups from around .75" to 1.25-1.50" groups. I tried everything I could think of to close up those flyers. Nothing worked. So I decided to do the last thing I know might work and that is a barrel tuner.
I found an all metal barrel tuner online that ran around $100 so I waited until I had the money and I was ready to buy it when I searched for it on Amazon and found this rubber barrel tuner for under $8. For 8 bucks I can be a big spender. I found a YouTube video with this product and decided to order it. I read the instructions and put a light layer of Ballistol inside the tuner and placed it over the barrel about 1" from the muzzle end. I chose a couple of average ammo choices and tried to shoot for groups. I first shot a 3 round group with Aguila Sub Sonic of about 0.50" at 50 yards. I increased the group size to 5 rounds and one round opened it up to about 0.75". A 10 round group was around 1" while shooting with a light wind. I was very happy with these results. Then I tried Aguila Golden Eagle which is the equivalent of CCI Standard Velocity. First group of 3 all touched!!! A grouping of 10 was 0.50". After establishing a baseline I now moved the tuner one half inch towards the breech as described in the instructions. Immediately the groups opened up noticably. I moved the tuner back and the groups tightened right back up. Next step is to try some real high quality ammo such as SK Standard + and SK Rifle Match which I have a supply of.
I am very happy with the quality of this product and for the price it works very well. I finally decided to shoot a group of 50 rounds and not try to wait for the wind to die down. So with the wind I shot a 50 round group at 50 yards at just under 1" with the Aguila Golden Eagle.
