Some folks here, have asked for my version of the LeGendre Side Crimp. This pic is from my cell phone and isn't close to the quality of Pitted Bore's and Hoots examples, but you'll get the idea.
My personal crimp is about .070" south of the case mouth and looks to be about .015" wide and is much deeper than most, for I open the collet cuts, with a fiber wheel on a Dremel tool.
Hope this helps..
