9mm to 10mm on a Progressive Press
Here's a video showing expanding, core seating, and notching on a Dillon progressive using BTSniper's die set. I'll post the point forming step on a Corbin CHP Hydro next.

9mm to 10mm point forming on Corbin Hydro
Here is the point forming step on the Corbin CHP-1 hydraulic press:

The press is cycling in Auto mode with Position and Auto Pressure Reverse switches set to On to control the diameter and protect the BTSniper point forming die against over-travel and over-pressure. The bullets consistently achieve the .3995 inch diameter die spec (and look pretty cool). The cycle timers are set conservatively (longer delays) while I learn the process. The system hydraulic pressure at the top of stroke is ~650 psi which calcs to 17,185 psi internal die pressure.
