Hodgdon does list 42.5 grains of AR2206H with the 139 grain Hornady Interlock for 2,857 fps in a 24 inch barrel. In an 18 inch barrel the velocity would be 2,700 fps, still good for an 18 inch tube but nowhere near 2,900 fps.
I used AR2206H as it was in stock in my powder cupboard and it is one of my go to powders.
