NONYA, I was just looking at the ballistic tables for different .308 bullets. I found that you can use the 155gr Nosler Custom Competition HPBT with a BC of .450 at 2800-2900fps and actually get better performance than the 168gr with a BC of .462 moving at 2600fps. It shows that there will be less drop out to 800yds, more energy, and slightly less deflection from the wind. Just something to think about...I have some on order right now. I'll post some info when they arrive.
