Results Summary

The Excel Biodegradable Tracer BBs again occupies the top of the chart, this time in roundness consistency. The surprising result here is the Ultimate BBs, scoring a poor 3.96cm roundness consistency despite an excellent diameter consistency. These results seem contradictory, but may be explained by the roughness of the UBB surface and associated minor blemishes which do not directly effect diameter measurement, but play a larger role in determining the rolling path of the BB in the roundness tests.
