I'm having problems with the ANGLE factor in the online version. I see that the input is limited to less than 89 degrees. But the affects on the trajectory looks incorrect. Using a Federal 30-30 150gr @ 2390 Fps at 79 degrees, the max height is only a few inches compared to an angle of zero.
Also, Hornady 30-30 Leverevolution is supposed to be a low BC compared to the Federal 150 gr FN. Both give sighting data on the box. Trying to duplicate their trajectories requires nearly identical BCs. I think someone is exaggerating?
My set-up - Marlin 336 with scope height of 1.94 inches, temperature and altitude set to default.
Info on the boxes:
Hornaday 160gr FTX - Muzzle 2400 fps, 100yds +3.0", 200 yds +0.2", 300 yds -12.1"
Federal 150gr soft point FN - Muzzle 2390 fps, 100yds +0", 200 yds -7.2", 300 yds -26.7"
Both of these require a BC of about .189 to match the listed results which I find odd.
If I sight in the gun for one how do I maintain this to estimate the performance of the other?
