fine detail green screen

Also what about filming chroma-keyed people from 50-100 feet away to be put into a crowd scene? Any problems?

If you're afraid you might lose too much detail in a subject you can always shoot it larger in the frame, and then shrink it into place in the comp. But if detail is too fine to be resolved in the comp anyway, you don't have to go nuts with the "oversampling."

Instead of CGI..(I know it can be done easier, but I hate easy)
I go to a range fire a semi-auto in front of a green screen (also paint the weapon green) and then composite the muzzle flash and case ejections onto the final scene.
Would that look right? Or would the detail be too small?

For things like flame/smoke effects it's not that the edges are too fine, but that there's a level of transparency to the edges. Dealing with transparent matte edges is really a post issue.
Gun flash elements should be easy enough to come by that you don't need to try to create your own. For one thing, the real thing usually doesn't look as "cool" as what you see in the movies, and it takes a munitions expert to alter the charges to get the right flash. And FWIW, transparent matte elements like smoke and fire are better shot against black instead of green.

And this will give you a good idea of how to deal with muzzle flashes in comp...
Hope that helps.
