I decided to use a White Super 91 this season,for at least one deer anyway.I just ordered a Lyman 57 peep sight and plan on sighting it in next week. I have never used a low charge ( 70 gr ) but after several posts decided to give it a try. Does anyone know what the trajectory would be if I sight in 3" high at 100 yards. I would like to be able to shoot out to 150 yards. 460 gr bullshop conical, 70 gr 777, 0r 70 gr pyrodex. Is 150 yards within the dead on hold with that load or do I need to up the charge ? I know in my 54 with a 425 gr and 90 gr I am ok, but since I don't have a crono to get velocities I don't have a way to check trajectory. I am guessing about a 12 inch drop from 100 to 150 yards.and if I stick with 90 or 100 gr about 4 inch drop. is this close Thanks
