The .38 loads that I see that work consistently from 2 inch revolvers are the Hornady Critical Defense ammo, be it the 90 grain or 110 grain in standard or +P. There are some other .38 short barrel ammo out there that work, but the Hornady CD ammo is available everywhere, it's a good price, and works so that's what I stick with.
But, I understand the concern with .38 in a snub because hollow point expansion isn't a guarantee. 148 gr wadcutters are better than nothing, but for me they're way too slow and if I'm going to rely on a non expanding bullet for defense, I stick with Inceptor ammo that's designed to work without expanding.
Inceptor is my main .380 ammo, which is about 57 grains of projectile going 1000 fps in an LCP. .38 Inceptor going about 1100 fps with a 77 grian bullet is even better.
