Ya, I still wonder about that also, if I had the time I would have switch sabot to the short black Harverster and that might have the difference. The HP24 is very long on the FTX although I have never had a problem with them in the past.
I will shoot them again someday when I am just out shooting, but the interesting part is even though they were tumbling they hit where the scope looked - course that was only 50 yards.
