The 303 Savage ammo that I had to fix last week also had horrible runout.   .005" to .008."  When I reassembled it, I did so on a nearly new Rock Crusher instead of my very old and worn Lyman Spartan.  Now the runout is .002" to .0035."  If I can get a Wednesday off when there's no tropical storm I'll have some decent ammo to shoot.
