I basically did the same.
I bought 2200 (IIRC), split evenly, or Missouri Bullet Co's 148-grain DEWC (#2 PPC) and their 158-grain SWC (.38 Match). And I load them both over 3.5 grains of N330. Which gives me a pussy cat 158-grain load (~750fps) and a warm'ish wadcutter (~800fps) from a snub.
But because my current go-to J-frame has a 2.5" barrel, I still carry 135-grain Gold Dot Short Barrel. Because from a 2.5" barrel it does what it is supposed to in terms of penetration with a good chance of expansion.

Both. Lead exposure is a higher priority, but a jacketed bullet load can also be carried for more years than you probably ought to, especially in nickel cases, without damaging the bullets. I did ten years of daily carry with one set of 5 in my 642 and one set of 5 in a speed strip. Anecdata and all, but those Gold Dots cranked off and made a little tiny 5yd group when I finally decided to cycle them out.
Xtreme Bullets has a copper plated 158 gr SWC

Underwoods 150gr Wadcutter provides a good number for a modern 'full charge.' Their ammo is loaded to full SAAMI pressure 17kpsi, whereas traditional wadcutters are almost certainly well below that.

From reviewers who chrono'd it, its averaging 870fps from a LCR 1.9" barrel. Another reviewer was hitting 990-1000fps from a 5.5" revolver.
I imagine they are using a slower burning powder to maximize velocity while keeping pressures down.
That is smoking from a snub.
I think the difference between the 9mm and the 38 wadcutter is the 9mm relies on velocity to expand and penetrate. The 38 only needs enough velocity to penetrate so it can be loaded lighter. This is the reason the milder wadcutter is preferred.
