Re: what's a good METRIC ballistic calculator? really like the G7 but its in yards NO
Coldbore 1.0 from Patagonia Ballistics allows english or metric units.
In metric units, input and output are:
Velocity in . . . . . . . . . . . . . . . . . . . . . . . . . meters/sec
Drop, Path, Wind Drift, Spin Drift, and Coriolis in cm
Turret click setting in . . . . . . . . . . . . . . . . . .mrad
Sight Height and Zero Height in . . . . . . . . . . . cm
Zero Range in . . . . . . . . . . . . . . . . . . . . . . .meters
Altitude in . . . . . . . . . . . . . . . . . . . . . . . . . meters
Temperature in . . . . . . . . . . . . . . . . . . . . . .celsius
I suspect other ballistic programs allow something similar, but this is the only ballistics calculator I use and am familiar with.
