Shouldn't take too long if you use the TMP, reloading when you're told to, and hitting them all (aim for the head if possible, but if you're running out of time, just hit them). And make sure you're changing between A, B, C and D whenever you complete a type! I got really frustrated six or seven years ago with the original game because I didn't get any bottlecaps, since I was playing over and over in A and it took me two or three days to notice...
