The best solution would be to buy a .38 revolver and load the WC in .38 brass, then buy some WFN (with or without gas checks) from Montana Bullet Co for the .357.
Because you were seized by the notion of .357 WCs, here's 150gr bullet data from the Lyman 50th Edition. I know they're not seated as deeply, but pressures are close to the old data posted above. Like @willie, I have seated WC bullets to a longer OAL. Looking back at my notes, in 1992, I must have thought WC in .357 would be cool, and I loaded them over 6.0gr of Unique. Apparently it wasn't all that, because I have never loaded them in .357 brass again
