Like ALL Vihtavuori powders made since 2019, N140 is both very temperature-stable, and includes a decoppering agent.
Have had excellent results with N140 in the .308 Winchester and M1 Garand loads with 150s, along with the 8x57 Mauser, especially the 8x57R with bullets around 200 grains in my Sauer drilling. There have probably been other good results, but those immediately come to mind.
