Despite what burning rate charts say, I'd doubt very much if this powder has the flexibility of H4895 and the same wide range of applications. It's a bit of an oddball in the Viht range and there aren't many niches where it fits really well.
It does work at least fairly well in small high expansion ratio cartridges especially with lighter or standard weight bullets - 221FB, 222, and the 223 with bullets up to maybe 60gn, and also in the big-bore high expansion numbers - 444 Marlin, 45-70, even 458 Win Mag. I imagine it'd suit the 20s like 20 Tac, VarTarg and simillar, but 204 Ruger and larger numbers are likely a bit too low expansion for it. John Haviland got good results with 223 and 22-250 with 55s and in 45-70 with a rfange of bullet weights plus 8mm Mauser many moons ago as reported in Handloader magazine.
I've recently tried my now elderly stock of it in 6.5 Grendel where it looks a very good match and had some indications of suitability, but it didn't work as well for me as N133. It did give around 100 fps higher MVs with the 120gn Scenar-L than N133 or Ramshot Tac, but they both give me more consistent results.
In between the 222/223s and big-bores, it'll work in the mid size range of cartridges with lighter bullets. Many years back I worked up an excellent load for the 70gn Sierra MK in 243 Win for a heavy barrel ex-police rifle.
Some of these Viht N500s are 'hot' numbers with high nitroglycerin levels. Barrel wear issues aside with full pressure loads, I've found them to be a bit prone to sudden pressure spikes on taking loads past normal full pressure levels, or even on having got there. So, a lot of caution should be taken with it and a close eye kept on chronograph readings looking for sudden lifts in velocities.
