There are a lot of difference loading for a gas gun vs bolt gun or single shot. Powder choice opens up because you don’t need to worry about cycling the action,
Bullet choice opens up without a magazine limitation.
How about a 250 A-Tip?

300 Blackout, not just for sub-sonics.

That's a huge bullet there. That would probably make loud thump in a Blackout.

Seating depth of .56" !!! Get a correct number. Measure YOUR seating depth.
GRT with the 180 and 14gr 1680 is 94% fill with .56" seating depth. 15gr is compressed and 57K psi. 10-11 gr 2400 will probably work better.
