David,

so he has to expain the neck to seat the bullet, right
So , he has to crimp it after seating..

So , it should be measurable as to what the crimp actually is?

What caliber is it? .308 ? something else?
For that caliber, there should be a specific crimp measurement, right?

I know for .45 acp , the crimp at the case mouth should be .470-.472
But don't know what his crimp should be , don't even know what caliber he's loading..
