I cast & load my own... easiest round in the handgunning world to make. And 148 gr wadcutters are damn good anti-personnel rounds, for your first cylinder. Which is what I carry in my 38 snubs.
They don't load worth a poop in a speedloader of any design. Stick with JHP's for your reloads.
I don't cast my own but I do use a speer HBWC loaded as warm as I dare (given the design) as my carry rounds.
I never bothered to chronograph one but they are going fast enough to hurt.
