question for firearms folks

Lou, I shoot a lot of 45-70s,, I run Winchester 300 grain through my Encore, it drops at least 6 inches at 100 yards,and starts a steady downhill grade on out. Past 300 yards I'm guessing now but I'm thinking 2 or 3 foot maybe more 300 yards and over, my Trapdoor I run the regular old 45-70 government loads with a 405 grain bullet. That one has the trajectory of a football. A lot depends on the humidity and barrel length. If you have the room get a roll of butcher paper and roll out some long targets to put down at 100,200,300 yards,shoot off a bench and let us know what you come up with. I will say this a 45-70 ain't going to shoot like a 22.250 but if that 45-70 freight train round even clips them they are going down

Guys thanks for the reply. I don't think I would even try a shot beyond, 200 yards. In fact, what I was thinking is to zero at 200, should be maybe 6 inches high at 100, or maybe zero at 150yards. I have several different rounds to experiment with. I don't have a place to shoot effectively, I do have a pistol range on my property, about 30 yards, but nothing to set up a rifle on. I did read one time that if one zero'd at 25-30 yards, it would be on at 200, but would, it seems to me to vary with the round in use, and, as you point out Tom, barrel length. I will eventually get to a range and play with the ones I have. But it would speed things up if I knew the ballistics going in. I'm trying to find the best grouping round with my gun, with the flattest trajectory, w/o excessive speed. I have watched several comparison tests of various rounds on Utube, some of the rounds are way overkill, they would destroy half the deer. I probably will eventually buy a single station Rockchucker and load my own.

I have a box of 'cowboy' rounds, has the balistics printed on the box: 425Gr FN lead bullet, 1000F/S at the muzzel, zerod at 100yards, down 12 inches at 200, 36 at 300!

Lou,here is a video on what your shooting. https://youtu.be/6t7EPeET3TU
