if it is the same bullet as the PPU 174gn 7.5 I have sued it for years in my K31 with RL17/RS60 out to 1000yds it has worked just fine, I don't load for .308 but in 7.5x55 the powder works very well with the heavier bullet, lots of folk use N140 so it should be fine with that if thats what you have
