True but unless you’re using a pcp that’s typically not an issue, the advertised velocity is nearly always exaggerated and light weight alloy pellets are used. Usually a .22 with average weight lead pellets (14.3 grain) should give around 800 fps +/- 50 fps depending on brand with spring pistons/nitro pistons.
Besides even if you have an airgun that can break the sound barrier it will have too much turbulence on the pellet to get any meaningful accuracy.
