I am using a Remington 700 Sendero in 300 win mag with a Leupold 4.5-14 mark 4 for my elk hunt this year. My rifle seems to shoot best using the Federal 180 grain fusions. I am trying to get some dope for that bullet beyond 500 yards. I am having a hard time finding the BC for that bullet. I am not even sure exactly what type of bullet it is. I have seen some places that call it a spitzer but it looks more like a core lokt. Does anyone have any good info on it or some dope to share. I have also tried some handload of 165 gr nosler green tips using 71 grains of H4831 in Hornady brass with less than impressive results. Any ideas will be appreciated.
