Thats what I started reloading with years ago. Great little tool and makes excellent ammo. Once in a while a primer might pop when seating it but there's nothing to worry about even then, just wakes you up. After seating the primer most everything else is just pushing, ie; the bullet, might use a slight crimp but then nothing is touching the primer.
Here's one way to look at it, if it was dangerous the lawers would have but Lee down years ago. More dangerous going to Wal-Mart on a Sunday afternoon.
