At the winter Loppet, I saw many inkastares lightly tossing horizontally to minimizing sliding on the snow - almost a gentle lob. A couple times this spring I attempted inkasting on my blacktop driveway - and was more successful when I used a similar technique. Kubb is a sensitive game - and drilling is a very aggressive technique. Sometimes I feel 4m feels to tight - and that I can inkast well and still hit a little further down the pitch. If you can still get a good cluster even if there's movement off the bounce - it's still good.
