I have already WMS conversion from 4326 to the same, and this works. Now I added another WMS map source with similar pattern, and with local projection instead of 4326, then WMS requests started to have completely wrong and defunct coordinate ranges. So it looks like 4326 (in source wms) ->900913 (in tiles API) works, but 3301->900913 reprojection does not.

Are you sure you are requesting tiles inside Estonia?
You should add a coverage to you source, if it is a local SRS, to make sure you are not requesting data where the transformation is invalid.
