There's been one in the family for a while and I kind of liked it, and did reload it with some nominal charge of fast smokeless --enough to go bang. The tactical implications of it were significant, though, because after using it, I realized how awkward side-breaking revolvers were to load and reload in comparison.
With the top-break, you just flip the barrel and the cases are extracted automatically to the point where only a flip of the wrist is enough to shuck out the empties, and reloading was much easier with the whole face of the cylinder open for a refill. I also loved the fact that the cylinder came off easily for cleaning.
Oh, and the fit, finish, and machining were outstanding on the Smith brand model. There's beauty there, even if you never shoot it. The rifling in that thing is mirror-smooth!
When I got a five-shot J-frame, I often wondered if the HKS 36 speed loader would have been suitable for fast reloading, but the S&W .38 is no longer immediately available to me to try it. (The .38 S&W cartridge case is slightly bigger in diameter than the .38 Special / .357 Magnum case.)
I did reload cut-down .38 Special cases for it, but (A)I had a lathe, and (B) the .38 SPL cases expanded a little too much for me to continue experimenting in that direction. In addition, the bullets were larger than .357, so I used
unsized .38 SPL cast bullets from a mold I had. One thing that bothered me about it was the bolt notches in the cylinder were cut directly over the chamber walls, resuting in an apparent (to me) weakness.
I've often thought that if they could beef up the locking system for higher-powered cartridges it would be almost ideal for a defense revolver from a fast-reload standpoint, and when I voiced this opinion on-line, someone pointed out that the Russians had made (are making?) a top-break in .357.
Conclusion? If I were in your LGS, I'd buy it, but only use factory ammo.

COMMENT:
My personal preference would be to go for the heavier bullet with slightly less energy with no other choices. But that's just me.
