I used Lee Alox over the Speer 158 grain swchp, and it did help, but not eliminate, the leading in my revolvers with that bullet.
For the guys reccomending full wadcutters, I completely agree and that's what is in my wife's j frame, with short barrel gold dots in the speedloaders to facilitate reloading,
exactly as someone mentioned above.
I would add this though, pick a wadcutter that has a sharp leading edge rather than a beveled leading edge. That sharp edged wadcutter performs better on soft tissue than the rounded edge and penetrates just as well.
