Muzzle velocity varies quite a lot based on ambient temperature, air pressure, altitude, and propellant grain size.

- regularfry 15y agoAh, so knowing the muzzle velocity might actually be a red herring - the turns per metre travelled is going to be a more stable metric.
- omegant 15y agoStill easier to have temperature and pressure sensors at the weapon( they fit in a wrist watch so there should be no problem to do the same at a high tech gun) and send a rectified time input to the bullet IMHO.
