I too have not been able to get the scirrocco to group well in my rifles.Then again the partitions and a-frames don't group a lot better either.Ballistic tips cut those groups down from the 1-1/2" to 2" range down to 1/2".I was really hoping nosler would offer the new accubond in lighter weights as I have no use for a 200gr bullet in my 300ultra or a 160gr bullet in my 7mmstw.
