Y'all Look at this: It will answer a lot of questions.

Pay special attn. to the bullet weights, velocities and trajectories.
Take notice the published trajectories for the 0970 (Segmented Quiet-22) is with zero set at 100 yds.

gemby58: CCI makes CB Longs. See above.

I use CB Longs as they are a bit more accurate than the CB Shorts in my rifle.
Quiet-22s are the most accurate in my rifle. I'm more careful about my "backstop" as they penetrate a good deal deeper.
I have 100 rounds of the Segmented Quiet-22; I just haven't tried them out yet.

DigitalDan did a good job of explaining a good bit of the BB, CB, etc. information. IMHO most of the crap posted on Wikipedia is just that. Crap.
