Sims LimbSaver® Sharpshooter X-Ring Barrel De-Resonator
the x-ring, as it is now called, is a great product. it will not make a load that your gun really likes that much better, but what i does do is take a load that your gun doesn't like and make it extremely accurate!
to the right are the results the x-ring had on my 17 hmr at 50yds. the before and after is dramatic. i can now interchangeably shoot two different rounds without fear of them not shooting the same!

This is my third one. I have one on every rifle that will accept one, a Remington .270, a Ruger M77 .270, and a Winchester Model 70 300 wsm. . Every rifle showed improvement in smaller groups and being able to repeat these over and over.

Limbsaver on the 243
Installed the rubber doughnut on my 243.......group size cut by 30% at 100yds......the tip about lubricating the thing is good advice!

1.5" to .24"
I got one of these for a birthday gift last month for my heavy varmint (deer/pronghorn) rig a Rem 700 VSF in 22-250. The rifle as is very accurate so I wasn’t expecting this chunk of rubber to help that much. So I tested it yesterday.
I started out with a clean barrel shooting Winchester Supreme 50 gr Ballistic Silvertips. I shot a three shot group at 100 yards with out the De-Resonator. The group was 1.5 inches. I cleaned the barrel and let it cool then installed the De-Resonator 3/4" away from the end of the stock. The next three shot group was improved. Again I let the barrel cool and cleaned the barrel. This time I moved the De-resonator a smidge closer to the muzzle. This group was tighter yet! After once more cleaning and cooling the barrel I moved it up a little more. ALL THREE HOLES WERE TOUCHING!!! The groups went from 1.5" to .24"
