In the seventies, I used to buy a 200 gr. factory "bluff nosed" round in .38 Spl.(made by Winchester, I think). I never used it on game, but in plinking, it was very accurate in my two .38's at the time, a Charter Arms snub and a Smith 6" K frame. I liked it, but I think it was discontinued years ago.
The trend beginning about then and since is to faster, lighter bullets, beginning with the old Super Vel line.
The 200 gr. British load was the substitute designed to replace the old .455 revolver round. The heavy, slow mentality was prevalent at the time and still has a remnant of supporters today.
Now, the high velocity, lighter bullets with rapid and controlled expansion are the rule of the day, because of the emphasis on defense and the studies done with gelatin and the tests of the FBI. Penetration is judged optimized for shooting human targets at far less than a heavier, non-expanding bullet will provide.
A heavy bulleted .38 Spl. round might have applications, but convincing the factories to produce it would be all but impossible in today's circumstances. Handloading is your answer, if you can locate a source for the heavy bullets or a mould to cast them in.
Oh, BTW, I just remembered that the "Old Western Scrounger" a few years ago sold some of the old style, heavy, "manstopper" rounds imported from Europe at atrocious prices. They might still have some for sale, if your bank account can handle the freight.
Hope this helps.
