I have used vN-340 for .45 ACP bowling pin loads, and it worked very well ... but was hard to find and expensive when I did find it. Data was not common for it either.
I have gone to Power Pistol, which I first picked because it was of similar performance in .45ACP and being an extruded powder like the -340, meters very nicely. I now use it for 9mm, heavy .38's, and .45 ACP ...... there are .357 and .38 spec loads for it (and -340) as well, but I don't like that little bit of powder rattling around in the case like a BB in a boxcar, preferring loads that fill at least half the case.....
I think that "one powder for everything" makes as much sense as "one tool for everything" ....... "If your only tool is a hammer ..... " .... there will be plenty of ruined screws.... IF much of anything at all gets done, it won't be done well.................
