Not scientific but may be of interest...
Yesterday before I read this post I shot a gallon jug with my 45acp; I wasn't impressed. The two different cartridges I shot, 230gr FMJ at 860fps and 185gr HP-XTP at 930fps, produced similar results.
Today I tried it with my 357mag and found the 125gr HP-XTP traveling at 1400fps did extremely well, and the 180gr HP-XTP traveling at 1050fps produced acceptable results.
Here is the 45 with a hollow point.
Here is the 180gr hollow point 357mag.
Here is the 125gr 357mag.
Another pic as the splash grew.
