Somehow missed seeing this thread? Well, it's not like there's exactly a dearth of threads on this topic.
I used to almost agonize over choosing the 'best' .38SPL load for my snubs in the 80's. I didn't expect the JHP's of that era to consistently expand, especially when fired form a 2-3" barreled snub. Like many of us, I eventually settled on one or another brand of the LSWCHP (later called LHP) +P, although I did enjoy using some of the Nyclad loads (once Federal bought the rights). I still have a supply of the Remington, Winchester and Federal Nyclad 158gr +P loads, but mostly favor the Remington, since they usually did best in the HC and 4LD testing (softer lead).
Nowadays, though, I favor (in no particular order) Speer's 135+P GDHP, Winchester's 130gr +P RA38B, and Remington's 125gr +P Golden Sabre. I've not only seen them do well in the hosted gel lab events at ranges, but they've earned good reputations among LE users.
For my Airweight that isn't rated for +P (37-2DAO), I stick with 110gr standard pressure loads, and have some 158gr standard pressure LSWC to fall back upon (only because I don't have any remaining 148gr Target WC left in my cabinets

).
I've tried a lot of other loads over the years, and wouldn't lose sleep if forced to carry most of them. Granted, a 158gr RNL or 130gr Ball would be my last choices, given my druthers.

I put my primary focus on accurate hits making the old service caliber effective. Not magic bullets.
Also, smaller revolvers generally demand more of the user, so more attention and effort to developing and maintaining skill is reasonably demanded of diminutive revolver users.
