Finally got a photo of a 15° taper crimp die I made.
The first die I made, and used for most shooting until now, was less than 15°. Not sure what I soused but closer to 5-7° I would estimate.
You can easily see how rapid a taper a 15° per side taper is. Compared to my Hornady taper crimp die it is way faster. The Hornady taper is hard to even perceive as a taper.
You can also see that this taper crimp borders on a roll crimp. This is a .468 crimp at the case mouth but the full diameter section of the bullet is not changed in dimensions to all.
