From Ballistics by the inch:

Delta Elite 10mm (5")
180 gr JHC BB 1,374 fps
175 gr STHP WW 1,209 fps

S&W M57 .41 Mag (4")
180 gr DPX CB 1,221 fps
175 gr STHP WW 1,108 fps

S&W M 29 .44 mag (4")
240 gr HS FED 1,094 fps
200 gr GDHP SPEER 1,009 fps

S&W 686 .357 mag (4")
158 gr HS FED 1,248 fps

Looks like the 10mm is at or near the top of the heap when compared to any revolver caliber with a 4" barrel (which is equivalent to a 5" auto after accounting for chamber length).
