rclouse79 Report post Posted October 18, 2010 I posted this question in another post, but wanted to put it on the main board also. I saw a couple of guys put the simms de resonator on their barrels and seemed to have good success. I am ready to test mine out next weekend. The instructions that came with the products said to place it closer to the end of the barrel if your barrel is free floated and closer to the stock if it is bedded. Most of the pictures I have seen have it placed closer to the stock regardless of the barrel type. I think they look silly, but am willing to give it a shot and see if it actually helps tighten my groups up. I have read enough reviews to convince me it is not a total hoax. Most people said they have to move the thing around to find the sweet spot before they see significant improvement. I was hoping people who have tried it would share the type of barrel they have (free floated or bedded), where they tried positioning it on the barrel, and the results they saw.

Red Rabbit Report post Posted October 18, 2010 I tried one on a rifle that had mediocre accuracy/precision. Regardless of where I placed the doughnut, there was no improvement in precision. Hope your results are better, as some have reported good success. Share this post Link to post Share on other sites
firstcoueswas80 Report post Posted October 18, 2010 I used to use one on my 257 but have since done away with it. It did seem to help, no matter where it was placed but an inch away from the stock is where best results were had. My action is bedded, and the barrel floated.

luvdemcoues Report post Posted October 18, 2010 I have one and all I know is without it my groups are around 2 inches at 100 yards and with it my groups are under an inch at 100 yards. I shoot a tikka t3 lite in 270 wsm. The doughnut is 2 inches from the end of the barrel. Share this post Link to post Share on other sites
