Rebjac,
You should be using a taper crimp die as your last station. Crimp (measured at the bullet case juncture) should usually be .468-.470. Through testing you may find your pistol prefers a tighter crimp, but ammo crimped to those specs should feed flawlessly. Don't try to seat and crimp in the same stage, these are two distinct separate process'.
On an added note, bullet seating depth can be puzzling at first. A general rule of thumb is to leave 1-2 thumbnail thickeness' of lead exposed above the mouth of the case. It doesn't have to be any more complicated than that.
FWIW
