my bullet are size .460 and when loaded the outside diameter of the case is .483
according to specs I am at maximum and the case don't feed they jam about 3/4 inches left to go in.
does that mean I have a tight chamber or I have neck thickening ( is it possible on straight case?
if so is the outside neck turning is recommended or inside neck chamfering
the thickness of the wall are .0013 to 0015 depending on the case
