    question for 458 owners

    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

    Before taking on case neck turning figure out first if it is the case, boolit or leade. Black sharpie can tell alot. Try with a 458 and 459 boolits too.
