I recently tested the CBC 168gr from a Savage 10, to compare with my Hornady and Federal Match (I shot some of the 147 grain CBC .308 as well)
100 yds, prone, bibod front, bagged rear. Millet 4-16 x 50 TRS, which was only used up to 10-power.
No wind / 28 degrees F / ammo temp went from 40 to 34 degrees over the course of the hour from the first round to the 25th-ish.
All the rounds came from the same box..
I had a set average of plus / minus 1/2 MOA between the Hornady and Federal. This was the BEST I could muster out of approximately 200 rounds of each, shooting in 90 degree temps to sub zero temps using this rifle and scope over the last year.
I was VERY impressed with the CBC by comparison, although I DON'T have access to a 500 yard range for better sampling.
The grand average of the CBC was 1/2" lower hits over all, compared to the AVERAGE of the Hornady and Federal.
The 147 gr. ammo shot 10 inches higher on average...wow.
