Where to sight in a 45/70 at 50 yds

I have a marlin 1885 that I loaded 350gr hornady RN moving around 1900 fps. I have no data on where to put it at 50yds . I think dead on at 50 will do .. I need to get one of those ballistic programs you use on the computer. Any ideas? .. Thanks Bill

I am shooting a pretty mild load in my 45-70 but if I zero it at 100 yards, It is one inch high at 25 yards and two inches high at 50 yards. I am shooting a 405 grain bullet at 1100 fps. That load is just 13.0 grains of Unique with a Magnum Primer. It is an accurate load in my rifle.

I would probably sight it in at 125 yards. Here are the ballistics.

If you go to the www.remington.com you can download a ballistic program called Remington Shoot. It is in the ammo section.

There is very little difference in the trajectory between the fp and RN. They have a very similar BC

I have mine sighted in 1" high at 50 yds also. I took the scope off mine and installed a Williams peep sight. Amazingly accurate out to 100 yds. I guess that's why the military uses them???
I enjoy carrying my 1895 guide gun and will be taking it for bear next week. Its like carrying an oversized handgun.
