Aaron Davidson explains how to use the ballistic calculator at www.gseven.com to print bullet drop data for various conditions on a field card to take with you into the field.
At the 2:30 mark, I wish there was a way to have all those drop values available to view simultaneously as it very much helps those new to using MOA and mil values, but being able to chose an option and print what is needed definitely gets the job done. Very good and informative video.
What is spectacular about this program is elevation can be in mils and windage in MOA thus a mix of mil scale reticle and MOA scope adjustment can be used for best range estimation off reticle and best address of wind appraisal from windage adjustment.
BC is so critical for accurate info as well as velocity. However, unless you are shooting, shooting, shooting, the data means nothing. You make a true DOPE card by shooting.....all weather, all temps. Not just those sunny, calm days....
Incline means shooting up hill or down hill. In either case the line of sight distance to target is greater than the flat ground distance to target and since it’s the flat ground distance to target which feels effects of gravity the sight must be adjusted to flat ground distance or the bullet will shoot over the target.
Noticed that the cards have angles in degress, for shooting to uphill, or, downhill targets. I have an angle indicator in cosign, not degrees. Can this program show cosigns of angle, or, just degrees of angle?
it works with any scope, mil or inch, which most scopes are 1/4 turn or .025mm for each turn, but again its more for long range, so you still have to put in the correct info, like Projectile coefficient, Hight above sea level, wind speeds, muzzle velocity, air temperature, and what caliber and most important what weight of bullet or grian like say a 308 with a hornet 215 grain bullet or projectile and then you have customise it as well poder used, rifle barrel twist ratio etc etc, it can be hard, but if you have the facts based on your rifle and where you going to shoot and the areas factors like wind distance etc, you should be able to adjust the scope and ammo tyo suit based on the rage your going to be shooting at ?
