Shootem:
I know exactly one guy who used to load plated 148 gr. wadcutters.
At the range one day, I watched him stack 5 of them, one after the other, half-way down the 6-inch barrel of a really nice K-frame S&W.
He said he used loading data for lead HBWCs. Low end of the recommended charge weights for B'eye.
FWIW.
