In the Lyman Reloading Handbook where the data chart is for the different calipers, etc. there is a BC: and SD: reference. What do these mean?

BC means Ballistic Coefficient and SD means Sectional Density. The complete definition of each term should be in the appendix of your Lyman Reloading Manual. It would be much easier for you to look up, than for me to type it all out.
