I have 7 J-frames at present, and have carried one or another of my growing collection since the early 80's.
While I used to put more emphasis on the ammunition than the guns, nowadays it's pretty much my skillset and abilities to effectively use them that get the primary attention.
Sure, I tend to like to use one or another of the better designed modern hollowpoints in guns suitable for those loads, but I often can't even tell you which brand/load may be in which of the snubs at any given time. Sometimes the spare ammo in my speedloaders & speedstrips match what's in the guns, and sometimes it doesn't. Sometimes I've even carried a couple different loads at the same time (different speedloaders/strips containing the different loads, grabbed from my drawer). The exception is my 37-2, as it only gets standard pressure loads and that narrows it down a bit in what I've bought.
I tend to prefer +P loads that run in the 125gr, 130gr, 135gr & 158gr bullet weights, and whenever I'm using up older & fresh loads at the same time for quals & training/practice, I commonly mix them up in my guns and run through the courses-of-fire & drills. My snubs exhibit similar POA/POI in my hands, using all that different ammo, out to reasonable drill distances (12 yds), and I usually don't have any problems ringing steel out to 50+ yds with any of my variety of +P loads.
Now, lots of folks have found that standard pressure 158gr LSWC or 148gr WC Match loads offer them better recoil management, controllability & accuracy in their J's (or Colt D's), and that's fine. It's all about consistently accurate rounds on the intended target, after all, right?
Now that we can select from a wide range of J options, lots of folks can better choose a weight & size that can better suit their anticipated needs, and even help them overcome the inevitable inherent disadvantages of the diminutive J-frames.
After all, some of the very attributes that make the little 5-shot snubs so appealing and useful for lawful concealed carry can also make them harder for many folks to shoot, even experienced shooters of larger revolvers.
Obviously, attention must be given to whatever the revolver manufacturers recommends in the way of ammo used in their respective products, and especially as it pertains to the ultra lightweight models (to help avoid bullet pull).
I used to look all over for specialty loads when I was younger, but nowadays I go through so much ammo for quals & training/practice that it isn't practical to limit myself to specialty or boutique loads that are more expensive than the major loads, and/or significantly more expensive.
It's just a snub .38, after all, you know.
