Lusche,A bit of topic,but have you ever done a graph on what planes kill what other planes the most?
I think not. I did chart most kills, kills&deaths, and I did what you are asking for selected planes (like the 262), but not in general.
However, the most frequent plane kill is one P-51D killing another P-51D and the most frequent kill overall is one Panzer IV killing another Panzer IV (based on this years stats up to and including tour 152).
Addendum: Top 5 plane kills Jan-Sep 2012
1. P-51D kills P-51D 20269
2. P-51D kills Lanc 12343
3. P-51D kills B-17 10050
4. P-51D kills Spit 16 9939
5. La-7 kills P-51D 9405
