I think the 137 is the best bullet hammer makes for the 308. I love shooting them out of my Kimber.If those 137s shoot good I wouldn't hesitate to run them for elk. Depending on expected shooting range. With hammers it's about impact velocity. The 150s will work to give you better impact speed at longer ranges but up closer might actually be slower and won't kill as well as a 137.
