    TrailBoss in the 300 Black Out

    Is anyone using TrailBoss in the 300BLK or 30-223 with the 200-245gr bullets?
    Looking for a few loads to try in a bolt action rifle.

    I got 840fps with 6.5gr of TrailBoss and a 150gr jacketed bullet. This was my available full case volume without compressing.
    I don't know if there would be need for concern of the powder volume displacement with a 200gr + bullet. But at least you can easily check to see if the bullet is stuck in the barrel or not.
