I fully agree about VVN110 and std. primers, as about the WW296 (with which I began) and magnum primers, then the 296 became unavailable here,
next I discovered that I could do .44 plinking even without pretending to be Elmer Keith_
and I learned more sedated solutions from your manuals and from your magazines, at the time.
Yes, all the manuals you mention are in my possession, and more, and the computer is certainly a great way to update it, even for me.
As far as I know, Vihtavuori has been acquired by Beretta, and Beretta imports this powder here, therefore it's the only quality brand widely available around here, if/when available, as the various primers these days, and not even I talk about today's ret. prices_
in any case I tend to work with components that I know and above all reasonably available, rather than studying any other powder, even better, generally Swedish or American, of which today I could find a pound and then never again for a year, as often happened here.
my poor trust on VV data finds reason in the suspicion that when VV entered the US market it boasted start-to-maximum performance achievable only with N110 doses that I prefer to avoid in my 29s, 27s and 19, especially considering my amateurish use, not hunting or silhouette comp., just to understand.
conversely I noticed that, in the absence of faster revolver powders at hand, the N110 itself can work well in 44mag. cases + cast in doses officially unsafe, below the recommended minimums, say at .44spl. recoil levels, without any problems and good accuracy, but these are my private games, byproduct of our gun-related laws that limit the overall amount of powder that can be held by a reloader, etc. etc._
this without questioning the validity of the official data, but trying to make the few pounds allowed work at their best, and taking into account that some rifle powder must also fit in my total allowed weight_
(I would really like fully answer you in Gaelic, but my translator has some limits
maybe some more Hennessy could help me, but I fear myself talkin'French next )
Kosh, thank for your attention and for the opportunity of some talk !
