I didn't see any discussion over this, so here it is.
Cheyenne apparently against all tradition, doesn't believe 'bugpin' in tattooing means a smaller needle diameter. Instead their tapers are spiraled.
7r 0.3mm = 7r bugpin 0.3mm
Take a look:
This spiral info was told to me by Cheyenne themselves at the last Paradise, yet they couldn't give me any kind of technical effect information other than a pompous "Our engineers disagree and this is best" with a thick accent. Ok- sure. Spirals might do something, but I sure haven't been able to tell what they do. But why label them bugpins at all? Anyone have an insight into this?
