I read about the Loudenboomer in P.O. Ackleys books, he designed it back in the sixtys. It looks like the most extreme in those books, and that was back when theywere really experimenting. Supposedly for the space program to see how different metals would hold together. It would be a good one to shoot at dusk, the muzzle flash may be a little extreme......

You may have to special order your dies though.
