Re: Rifle Barrel Harmonics Mitigation
I use the SIMMS on all my rifles, and have found that they help bring that last "little bit" of accuracy. I agree that tuning the load to the rifle helps also, but the de resonator does the rest. Takes a little experimenting to find the sweet spot, on .300RUM the ring likes to be up close to the stock, the Hvy bbl .223 and 22-250 like it about an inch further out, and .243 ai wants it about 3" frome fore end. None of my rifles like the "donut" out by the muzzle.
