Nice shootin Jack!!
Using BC calculation software, the LE 45-70 ammo has a BC of .234 when muzzle velocity is the stated 2050fps, but the actual 3-shot average is 2012fps as recorded over a chrono from the 24" barrel as reported by a shooter on another site. So using that BC, here's your
calculated trajectory. It would be very wise to shoot it at 200-300yds to confirm the trajectory tho, that's the only way to know for sure. I had to adjust the zero range to 162yds to get the 3" high at 100yds to work.
