So
you are into reloading and you wonder how well that little package with
77 grains of IMR 4350 powder behind a 300 grain round nose, full metal
jacket bullet will do. Well, you can do two things, a little bit
of physics calculations, or go out and touch it off, hoping that it doesn’t
explode in the barrel! I would choose to do a little physics myself…
By using some basic physics equations, you can figure out just about any
part of the rifles ballistics data. For instance, if you know a few
variables, you can predict range with physics, or if you like you can figure
things like drag on the bullet, pressure and expansion values inside the
gun, on the bullet and much more, all from physics. For this web
page, I will stick with simple stuff like energies and range.
