TAC in .223, black rifles and bolts.
IMR-4064 in .243, 6.5x55, .308 Win can be used in .270 Win.
Haven't settled on slow burner yet, considering Reloder 17, 22, 25 or 26, IMR-4350, or maybe Accurate MagPro.
Have had surprisingly good results with Alliant Power Pro 4000-MR in .270 Win. Might try it in 270 WSM and .300 Win Mag
