IIRC one of my students did a research project for the college on ballistics and they used a 55 gallon barrel for .32 Acp, .380, and 9mm handguns. They stood on a back deck and shot straight down into the barrel.

I recall him saying that the professor that was mentoring him said that a 55 gallon drum also stopped expanding ammo ( soft points ) in every rifle cartridge he tried.
