This statement indicates that you really don't know what a harmonic dampener is designed to do. The majority of rifles will shoot a few loads well. A harmonic dampener is a method of tuning a firearm so that it shoots a much wider variety of loads and bullets well. With .223 bullets running in the 40-80 grain range to be able to adjust the gun to get the maximum accuracy out of each of them rather than just a few in a limited weight range is a major plus. Does it take some work to find the sweet spot - of course it does, but at least you have that option. A rifle without this feature will never shoot certain loads acceptably because you're stuck with what you have. I'm sure if you had tried enough factory loads in a wide variety of bullet weights one or more of them would have been tack drivers. Getting any rifle to maximize its potential is not a job for the impatient.
