Biovals are absolute Trash.
They arnt spun during the moulding process, causing air bubbles to form all over the BB's causing an imbalance in weight which ultimately causes unpredictable flightpaths.
When fired, they shoot straight up till about 10m before they shotgun all over the place.
Its like firing Metal BB's at a superconductor Magnet set to repulse.
