    "... I discovered why Henry's shotgun cannot be
    accurate with the commercial rifled slug-the slug did not
    fit any part of his choke-bored barrel; the cylinder portion
    measured .731" and the muzzle .705", while the rifled slug
    averaged .685". This made it a loose .046" in the cylinder
    and .020" in the choke. Thus, the slug was certainly safe
    to shoot even in a tighter choke, but never accurately,
    hecause each shot would strike the taper of the choke
    constriction at a different point, resulting in a deflection
    from the line of aim with practically every shot. The claim
    that the slug expands to the diameter of the barrel doesn't
    seem to hold water."
    -----------------------------------------------------

    That is why George Vitt set out to design a better shotgun slug back in the late 1950s.  His slug design stayed on the handloaders market from the early 1960s until the 1980s.

    US manufacturers finally increased the diameter and thus accuracy of common "rifled slugs" in the eighth decade of the last century.  Wow that was some 40 years ago!    :o

    Oh yeah, here is an updated Classic Guns link to the article on page 29 of the   December 1963 issue of Guns Magazine:

    It is truly amazing what passes for "knowledge" among people who should know better.  I guess it begs the question: how many times do we have to "discover" there is no substitute for the hard work of compiling empirical data - particularly in technically oriented fields.   :facepalm
