I tried it, I started around 53 grains and worked up. Showed promise, but I have 24 pounds of reloder 26, so that's what I use for mine. My barrel is very slow, I was using 57 grains of reloder 26 for 140s @ 3050 FPS. I shoot right around 55/56 for the 156s. This is out of a Christensen arms ridge line
