This is all in the manual, Bruce...and lots more you will need. Have you 
downloaded one?  If not try this one: 
http://bama.edebris.com/manuals/military/an-arc5/

I could give you all that from the manual, but under the "teach a man to 
fish" principle, this might be a more productive path for you, 
especially, since the answer is - "it all depends...":-)   See 
paragraphs 1-19, 4-14, 4-27, and Table 6-3.
