Can anyone tell me the drag of a standard bullet? I realize there are lots of variables affecting this, but what is the ideal amount of drag without considering particulr weather conditions.

Of course, you correctly mentioned that numerous factors affect the Drag Coefficient. Keeping that in mind, the following NASA site provides some "typical" values you might find useful. Values in the literature generally range from Cd=(0.2) to Cd=(0.4), with Cd=(0.3) somewhat typical for usual trajectory and environmental parameters.
