Does anyone know what load would work with TrailBoss powder and would 125 Noslers work sub??

Do not use Trailboss with the 300. Use H110 for super and VV N110 for subs in your bolt gun. Use the Trailboss in a 308.

If you are going to shoot 125s Trailboss or Tin Star may work and will be stupid quiet, but the 125s will not expand @ 1050. You may look at:

There are loads listed for Hornady VMax 110's that are sub with TrailBoss but definitely won't cycle an AR. Once you get to the listings for NBT 125's it's all super because of needing the velocity to expand, otherwise save the money and just shoot FMJ's.
