I finally figured out how to get a decent crimp out of my tool.
First your stack height has to be correct. You can figure this out if you have a regular shotshell loading press and do everything on it up to the crimp. This will show you where the stack needs to be so you can duplicate it manually.
I used a LEE Pre crimper to start the crimp. However you need to squash the crimp down pretty hard to where there is only about an 1/8-3/16 hole in the middle.. This takes multiple pushes on the crimp starter. I used my Little Sinclair Arbor Press and had to get pretty serious with it in order to get the crimp started deep enough to translate into a good finished crimp.
The secret was getting the Crimp started deep enough, the rest took care of itself.
You can easily see these crimps are more than satisfactory.
