I have had several presses and have had my Rock Chucker for over 40 years. First thing I did was throw away the priming arm.
I use nothing but a Lee hand priming tool and prefer to use it even when loading ammo with my Dillon 650XL.
Nothing can match the 'feel' of seating a primer by hand.
You can instantly tell when the pocket is oversize, etc.
You can never get this feel with a press.
