Until last year when I purchased a Tikka T3x Superlite , I have not owned a .270 Win since 1963 (app. a 60 yr hiatus). I loaded H4831sc under a handful of different bullets and it worked as advertised.
However, I also wanted to try a new powder with anti copper fouling properties under Barnes bullets. I ended up with 56 grs. of StaBALL under 130 gr TTSX @3076 ft/sec. With multiple sub MOA groups, that is all I needed from this rifle to be a very happy guy. I took this load to eastern Montana and easily tipped over a goat at distance without any drama.
