Re: Leica's New Geovid HD-B
In the GSeven ballistic program you can either use the G1 BCfor your bullet or the G7 BC for your bullet to develop your turret/program. But on the Leica GSeven program, you can onlyuse a G1 BC for your bullet.
I had used the G7 BC to develop my turret. I chrono my load then shoot my rifle at 300,400, 500, etc. and record the MOA turret settings. I then input my data (velocity, BC,temperature, etc) into the GSeven ballistic program and run the program. I then check to see if their impact pointsmatch my MOA turret settings at all of the distances that I shot at. They usually do not match exactly. But you can either change the velocityslightly or change the BC slightly in the program to get a ballistic programthat matches your bullets impact points at each of the distances that you haveshot. Gunwerks has a YouTube video thatexplains how to do this but I think this explains it. You just change the BC or velocity slightly,rerun the program and compare to your known impact points. You keep doing this until it matches.
You do the same thing on the Leica program. (Which is theGunWerks GSeven program) you put in your G1 BC (they do not have an option fora G7 program) velocity, etc. that you have for your turret/load and it willshow you what the turret settings will be for all the various yardages. If it does not match your turret settings(which you know to be true since you have shot and recorded them) you “tweek”either the velocity or the BC to the point that all of your turret settingsmatch the program.
All of this establishes the “base line” for theprogram. Once in the bino/rangefinder astemperature, altitude/angle, etc. changes, it will change your impact yardage readout.
I have tried my Leica at various extreme angles, distances, temperatures and have found the corrected distances to be very accurate.
