I saw samples of 0.5mm, 0.55mm, 0.6mm and 0.65mm. The 0.5mm claims a 6.3 to 7.2 elongation factor, while the 0.55 and 0.6mm state a stretch factor of 5.8 to 6.4 times resting length. The 0.65 can stretch 5.6 to 6.5 times. Not made in China but in the Czech republic, it is tested down to minus six Celsius so is created for use in the cold. Frank Wass is shooting a seriously rapid 315ft/sec with 8mm steels with his cut and draw and rates it very highly.
