Trcioo:
You’re right, it was the diameter in inches not the area, the area is 0.00231. It is getting way too much force now, initial speed is 830m/s. I think I’m getting the unit conversion wrong, do you mind in take a look in the project? it’s a 2MB size with 1 projectile blueprint inside: google drive link .
Can’t check it now, but take into account that ballistic coefficient doesn’t equal air drag coefficient. They are different. Don’t know conversion but formulas at the beginning can be helpful:
In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass. BC can be expressed with the units kilograms per square meter (kg/m2) or pounds per square inch (lb/in2) (where 1 lb/in2 corresponds to 703.069581 kg/m2).
