I like the idea, but I've read and bought into @Mas's thoughts on the use of non-factory loads for self defense. And I've already got a couple hundred rounds of 170-grain LSWCs loaded to .38-44 specs.

I have not done any real testing of that bullet in .357s.
I have a supply of new .38 Special Starline brass, and FAR more people shoot and buy .38s than they do .357s by a very wide margin.
I would do up some .357s but acquiring new .357 brass right now is like trying to find a reasonable redheaded woman at an ANTIFA meeting.
Fortunately I am actually a licensed manufacturer. I just do small scale stuff currently. Eventually (if the people I paid a stupid amount of money to will get it done) I will have a website, but right now the locals keep me busy.
Its an odd business though, trying to gauge what people want. What they say they do, and then what they will actually buy are often two very different things. 95% of the shooting public will load virtually anything that goes bang into their guns, even for defense purposes.
I made up a batch of 9mm that was meant as a bear/outdoors defense load, that would also be great for use against vehicles, back when we were having all the riots last summer. It used a Rim Rock 147 grain hard cast Flat Nose at around 1100 FPS. Exact same bullet that Buffalo Bore uses in their +P 9mm OUTDOORSMAN load, and same velocity range.
The locals, even sportsmen going into the mountains, just wanted the cheapest FMJ or poly coated lead they could get. I even explained that the hard cast @ 1,100 was a better choice and a fraction of the cost over BB. Nope, they wanted walmart style ammo.
Figured out right there that I would probably concentrate on mostly revolver ammo, as the 9mm specialty stuff was a bit pointless for 95% of the market. Plus when the big outfits get caught up, you can't compete with the production capabilities, and what they pay for components (plus they make the primers) so making wadcutter .38s, .44s, specialty .45 ACP, etc and other specialty (fun) stuff is a better way to go anyways.
If the load is standard pressure, rather than +P, more than 830 fps is highly unlikely from the 4-inch vested test barrel or an actual service revolver. From a 1-7/8" S&W J-frame typical of current production it might make 700. From a 3" S&W Model 13 maybe 800 if the cylinder gap is at Mean Assembly Tolerance, not over 0.006", but most of the ammunition factories quit using the 4-inch vented test barrel by the year 2000, because nobody was ordering contract quantities of revolver ammo which required its use.
For normal commercial production most manufacturers went back to the older, easier to use, solid test barrel which produces that higher (unrealistic compared to a revolver) velocity number which the marketing guys love to hype. I expect THAT is where your 830 fps number comes from. I eagerly anticipate chronograph data with measured barrel lengths and cylinder gaps, firing in both 2-inch and 4-inch barrels, comparing this load side-by-side on the same day against established standards of factory ammo, such as the Winchester X38SPD 158-grain lead HP+P, and on the low-end, anybody's big-3 US brand 148-grain midrange target wadcutter.
This absolutely matches my experience.
Data from factories I found out was obtained using a 7" unvented test barrel. Compared to shooting in an actual revolver, using various barrel lengths, the factory listed velocities were grossly overstated. In fact on one powder manufacturers website, their data, versus actual field data, confirmed using two chronos ( that averaged within 6 FPS of each other over 20 shots), showed the factory data to be overestimated by almost 300 fps when using 125 grain lead truncated cone .38s. If I recall right it was around 285-290 FPS average.
Pretty dang far from what they said that their load would produce, to say the least.
