Span classnews_dt09062012spannbsp018332i just went from what i thought was a 7mm to an 8mm stretchgauge but it felt like it is already adjusted to the size was i meant to feel anything at all going from 7mm to 8mm or is it possible that my local piercer gave me two 8mm talons i measured them as well 1mm difference however the depth is different on the 7mm.
