Trailboss is a popular powder for loading traditional black powder cartridges (rimmed rifle cases) and also subsonic 300BO. It is a very clean burning powder. The powder is designed to be bulky to replicate the larger case fill that traditional black powder would take up in old lever gun cartridges. As a result it is good option for subsonic... good case fill with lower powder volumes compared to spherical or stick powder,
There are some other powders that may deliver top accuracy (supersonic) without having to max out velocities.
