LimbSaver Sharpshooter X-Ring Barrel Dampener, Standard Barrels, Black

Works great and improves accuracy when dialed in.

For background: I own a 1987 Browning BAR in 7mm Remington Mag (No Boss on these years). I have done a TON of research and reading on reloading for long range accuracy. I have been handloading for a couple years (not an expert, but I know a good bit). I have tried many many loads for my BAR trying to get sub MOA (1" at 100 yards) and I could never get it to pattern like I wanted. It would be ~1.5" - 5" depending on load. For those into reloading: I've measured lengths and tried different offsets, different powders, etc etc.This last weekend I shot my Sierra gameking 160's with H4831 - 2-3" pattern from a rest at 105 yards. I slide on the Limbsaver to the suggest location (just forward of my stock), put it on the rest and fired 3 shots: <1" (maybe 0.9"). I let my barrel cool and fired 2 shots 4 minutes apart (to cool the BAR) - the holes were touching.Completely blown away - but it worked for me. My BAR is a sub MOA!NOW: as a reloader I know that maybe I never found my sweet spot for my gun, so if you are putting in <1" pattern already, this is not going to do it. But if you are having poor results (and you know it's not you, the load, the scope) then give it a try for so little $ invested. If it doesn't work return it.Update April 2015: I'm glad this has been helpful to people! I wanted to provide an update from my original review. I have had this on the rifle for at while now and with it in the same place as noted above I consistently shoot tight groups (Tight to me with a BAR is <1" at 100 or 1 MOA). I have even thrown different hand loads through it in quick succession (The bar is sensitive to heat) and it continues to perform! Love it. I was going to drop $800 plus on a bolt action rifle to get better accuracy, but I'm loving the bar now!

Seems to work.

will do what it says. can reduce group size.

Transformed and old 270 from a 2.5 MOA rifle into a 0.5 MOA rifle. Transformed a 1.5 MOA 223 rifle into the same 1.5 MOA rifle it started as. When they work, it’s magic. When they don’t, well at least the product is affordable. Worth taking a chance.
