This info is for my rifle only!! I use 71grs of VV24N41 with the Nosler 140gr AB bullet, CCI LR mag primer. 3228fps over my chrono . My rifle is a Win 70 EW 26" Bbl., 1/9 twist. Similar velocity can be attained with US-869. But since US 869 is slower burning it takes a few more grains than the 24N41. Hope this is helpful.
