I am getting conflicting results with all of my ballistic calculators with this particular load... I know my bc, know my velocity and zero but somehow my calculators keep giving me consistently incorrect elevations. I am putting in all the correct information including altitude, humidity, temp and pressure, but somehow my rifle consistently shoots differently. I don't mind if it's a little off but I'm wasting time and ammo walking them in when my calculator gives me wrong information. I even had another professional shooter calculate my elevation and at 1100 yards he was 6 minutes high.
I am shooting a 300 win mag with 208gr Hornady match with a .62bc at 2984 fps at 6300 altitude. I know my zero is at 100 yds, 16.75 minutes at 850 yds, 21 minutes at 1000, 26 minutes at 1100. These figures may be a TINY bit off but when I dial my figures in I can get first shot hits but with the calculators I have to walk them back several minutes. Should I just put in a fake bc untill I get a table near what I am getting ot just make my own table and carry it with my rifle? Id sure like to be able to type in a range into my calculator and be at least close to my target.
Any input or similar experiences would be appreciated.
