I agree with your concern (auto vs revolver) there's a lot to remember with the semi as compared to the revolver.
As far as WCs: many years ago, Blazer offered 148 grain WCs in little plastic ammo boxes @ dirt cheap prices. I bought a bunch, as my models 60 & 19 both liked them. When I got a Model 38 (airweight) I found out they recoiled more than my non+P 158 grain SWCs. I've never put them over a chrono but they seem to be more like +P, so all WCs are not mild.
