Target / Distance information?

Where can I find the various target / distance descriptions for bullseye?

For example Target B2 is to be shot at 50 feet. But for which portion? (slow, national, time, or rapid)
Does it matter if you're shooting .22, center fire, or .45?

Where can I find the other target / distance combinations that can be used for bullseye?
Would also like to know what stage to use each combination in.

Thanks,

The rule book has all of this information. You can download or view the rule book for free here: http://programs.nra.org/documents/pdf/compete/RuleBooks/Pistol/pistol-book.pdf

B-2 targets are for 50' slow fire with either RF or CF

B-3 targets are for Timed and Rapid fire at 50' with either RF or CF
