Hydrotec appeared to be a tray molded PLA solution, which would enable high quality shells in a variety of geometries, but the fill is prohibitively lacking in density, which gives a poor ballistic coefficient. Something like a Hydrotec FSR in 50 caliber would, perhaps, have a balance of accuracy, payload, and cost. I would also recommend they orient the seam along the front of the ball rather than their current top and fin motif - the breakage from a lighter round would be improved significantly with a seam always hitting first.
