OT: on plated DEWCs - a few years back I did a fair amount of experimenting with these over various loading, in search of a defensive wadcutter loading. Found that the max standard-pressure .38 Spl loading of Unique (5.1 grains, standard primer, .38 case) gave me the best results in terms of accuracy and power.
Then a friend of mine tried the same thing with hardcasts. Let me tell you, Tennessee Valley Bullets hardcasts outperform the Rainiers (which outperformed the Berry's in this and every load from every gun for some reason) by a notable margin. I bought a mess of TVB WCs and have never looked back. (I'm still burning up Rainiers on target loads.
)
Just FWIW . . .
