I am a big Vihta Vuori powder fan, that said I wont ever use the 5 Series powder's again. they are a double base powder but are really rough on barrels more so than other double base powders. The 1 Series powders are awesome but not as popular as most powders just because they are normally more expensive. The N150 you mention is in a burn rate close to H414/W760 and the various 4350's.
I use it in 22-250's but it has quite a wide range of application
