I don't use lead for my Taurus 431, so I can't help ya there.
My plinking load is Sierra 200gr JSPs over 6gr Bullseye. Accurate, not painful or punishing at all (even with the original wood grips), and wreaks havoc on innocent fruit and eggs.
"If your determination is fixed, I do not counsel you to despair. Few things are impossible to diligence and skill. Great works are performed not by strength, but perseverance."
-- Samuel Johnson
