Bullets: 200 gr. plated flat point from berrysmfg.com:

Powder: Hodgdon HP38, 5.8 gr.
Primers: I used Winchester WLP, but whatever large pistol primer you have on hand will probably do well.
This load feels not quite as strong as factory 230 gr. ball ammo, but it is probably due to the lighter bullets. There's a bit more flash than with 230 gr. ball ammo too, probably since it is a lighter bullet, sometimes the powder is still burning a bit when the bullet exits the barrel.
I've seen it printed that plated bullets should be treated as cast lead, but I've found this not to be the case unless they are the same diameter as cast lead. They tend to be 0.451" and not 0.452", so I treat them as jacketed, as far as load data is concerned.
