I ran the H4831 with the 210 Bergers and 208 Amax and had great results with my group from both. The Amax was a little better but I was not happy with the speed I was getting. With 67 gr of H4831ssc I was only getting 2580 fps. The target below shows what the groups were looking like at this speed but I am taking this gun out to the 1000yrd line and wanted to get the speed up to around 2800. As I increased the powder the group opened rapidly with the Amax and Berger. All that being said I went to H1000 and am getting the speed and the groups are almost as good. This is out of a first generation Sendero.
