My SAK one doesn’t take any velocity away from the .17 HMR, average MV with the 17gr V-max is just over 2500FPS, from a 19" CZ 452 Varmint barrel.
As for effectiveness of the moderator, its just the same muzzle report as a moderated .22LR, just a "Pffff", but with all the downrange 'crack' from the high velocity HMR round.
In the wind, check out the ballistics data as it may surprise some of you, the little boat tail 17grain V-max has quite a high ballistic coefficient, that combined with its high speed makes it superior to practically any other Rimfire round in the wind, including the .22WMR. Competitions center fire shooters may also use heavy bullets because they are longer which allows them to have higher ballistic coefficients than the short, light weight bullets.
Edit, also regarding noise unsuppressed, the HMR is like a 12guage shotgun for noise. Certainly makes your ears ring the same without protection!.
