Both the 160 & 185 Ttsx shoot well out of my rifle. My current 185 load is 47 gr. 8208 XBR, starline brass, WLR primer, set to .05” jump. Accuracy is outstanding in my rifle. At this time I’m planning on using this combination for an upcoming moose hunt. I have faith that the 185 ttsx out of the 338 federal is a good choice for moose size critters.
