There seems to be a noticeable divide in reaction types on a lot of those kinds of targets. The .38 special and .32 H&R Magnum are on one side of the divide with .327 and .357 on the other. Once you move up to either the .327 or .357, at least in usual weights, hollow-points start having more dramatic effects on fluids. Containers rupture more violently. Damage to solids increases too. I don't have a chronograph so I can't give you a magic number. It's just a generalization based on what I've experienced.
Of course, as jfruser said, muzzle blast increases too.
