44.0 gr RL-15 works with 155, 165, 168 SMK, and 175 SMK and A-Max.
If the EU is allowing RL-15, how about Alliant 2000-MR? It is dense, so you can put more into the case, slower burning, and will push the 155-gr SMK at a very accurate 2,950 FPS out of a 24-inch barrel .308 Win, like my Steyrs. 47.5 grains will launch a 175 or 178 at 2,750.
