I still believe from my own observation of .177 cal diabolo pellets, that for this calibre, the magnus effect is either non existent, or so insignificant as not to be taken into account.
The reverse applies to cylindrical bullets/pellets.
That might explain this - see attached photo -
Shot at 100 yards with 9 o'clock i.e. full value left to right wind

Any explanation as to why diabolo pellets are opposite to cylindrical bullets/pellets ?
