Here I shoot my HMR with a fancy 17 cal specific Wildcat Evolution (centerfire mod), a cheap Edgar Brothers Sirocco and a premium quality Calibre Innovations A.R.M.O.U.R MKI
None of them make it quiet, the Wildcat Evo is clearly better than the other two and the Calibre Innovations offering does a better job than the Edgar Brothers, but there is no such thing as a quiet HMR.
