480 Ruger & 475 Linebaugh shotshell loads?

[Naphtali]

Does any manufacturer sell 480 Ruger and/or 475 Linebaugh shotshell loads? If none does, has anyone a procedure to make them using #12 or #9 shot? I prefer to take advantage of the cartridges' overall lengths -- in a similar fashion to Speer's capsuling of shot -- rather than limit payload to what fits within the case proper.

none that i know of but heres a thought to try. Ive heard of people using 45acp brass seated with the head out and using them for plinking. Why not seat one base first fill it with shot and cap it with a cardboard wad and a light crimp. Load it with a light load like 3 or 4 grains of bullseye and id bet it would work.
