Can someone use their ballistics program figure out how many grains of Unique and/or Trailboss it would take to produce a subsonic round with a 300 win mag.
Forgot to add, i don't know what bullet to use because most need more velocity than subsonic can provide, but it has to be less than 190 grains.
