I recently acquired a Leshiy 2 .25 and tried multiple slugs (not pellets) and two seem to stand out, ZAN .253 Cal 38gr and the JSB Knock Out 33.5gr, which is a .251 Cal. The problem with the latter is that they fall out of the mag, and the former is a bit too tight but still shoots well. Does anyone know if there is a great .252 Cal slug? That would be the perfect cal for the Leshiy 2.
