I use the Lee Factory Crimp die, so I'm not familiar with the Hornady die. To check my crimp, after seating the bullet I measure the case just at the mouth, then adjust the die to create a crimp of about .005+. To check the tightness, you can place the bullet on the edge of your table and press against the base of the cartridge. If the bullet stays put, with a few pounds of pressure, it's probably crimped sufficiently.
