They are pretty proud of the 175 SMK.. the story on how the "168" became the standard for 1000yd shooting is interesting. In short one of the top shooters of the time shot a world record with the 168 SMK and everyone started using it. Even though it's not ideal for 1000yd shooting. Across the course with a m1a yes. The 175 offer a better BC but, the 175's have the same BC as the 88gr eld-m. If you are using the 224 Valkyrie or 22 nosler heck even the 223/5.56 it's all a wash. I'm shooting 90gr Sierra's from a modified mag in my AR getting close 2500 FPS with H4895.
