Trail Boss Powder

[Xbow hunter]

Anyone know of any reputable online sources or trail boss powder. I am new to getting into reloading some subsonic ammo and am trying to avoid getting ripped off. Thanks

Supposedly, trail boss hasn't been produced in the last year and doesn't look promising for the near future. It occasionally pops up on Gunbroker, but goes stupid high. Unique is another good option.

Thanks, may have to give up on the 308 subsonic and get a 300 blackout barrel for my pro hunter rifle.
