Revolver guy here. I'd crimp this one right at your left-most "crimp" line as indicated in photo. Make the crimp roll right over the bullet radius at that same spot - not into the bullet, but just over/right at it & leave the truncated cone sticking out of the case. 'Course, as mention, you could shoot this one "backwards."
Don't "get" why this one has such a leading profile, as all WCs shoot just fine as a straight cylinder. Nothing the matter with whatever floats a boat, just "curious" is all.
Curious as to what you're paying for these. Speer/Hornady have WC/HBWCs at ~$7/250 - bulk, light-lubed, swagged lead that will shoot the eyes outa flies at 25 yds.
