Abstract
An apparatus, system, computer-readable medium, and/or process to measure, sense, or otherwise obtain weight of a projectile and use that information to generate instructions to adjust aim of the projectile. For example, instructions may indicate a desired weight of a projectile for performance.
Claims21
A non-transitory computer-readable medium storing instructions, which when executed by one or more processors, cause the one or more processors to:
- receive, from a digital scale, a first measured mass of a first bullet and a second measured mass of a second bullet, the first and second bullets to be of a same bullet type;
- determine a first ballistic coefficient for the first bullet and a second ballistic coefficient for the second bullet based, at least in part, on the respective measured masses, wherein the first ballistic coefficient and the second ballistic coefficient are to be different;
- compute a first aiming adjustment for firing the first bullet toward a target and a second aiming adjustment for firing the second bullet toward the target, wherein the first and second aiming adjustments differ based, at least in part, on the first and second ballistic coefficients;
- and provide, to a user device, first and second instructions that indicate how to modify an aim of a firearm based, at least in part, on the first aiming adjustment and the second aiming adjustment.
1 more element
A system, comprising:
- one or more processors;
- memory to store instructions, which when executed by the one or more processors, cause the one or more processors to:
- store measured weights of a plurality of projectiles of a same type;
- store data including results corresponding to firing the plurality of projectiles at a target;
- generate a model to correlate the weight of the plurality of projectiles to ballistic coefficients based, at least in part, on the results corresponding to firing the plurality of projectiles at the target;
- receive measured weights of a first projectile and a second projectile to be fired, wherein the first and second projectiles are of the same type and have different measured weights;
- and generate a first expected trajectory for the first projectile and a second expected trajectory for the second projectile based, at least in part, on the measured weights of the first and second projectiles and the model, wherein the first and second expected trajectories are different.
4 more elements
A method comprising:
- determining weights of a first bullet and a second bullet, wherein the weight of the first bullet differs from the weight of the second bullet;
- determining a first ballistic coefficient for the first bullet and a second ballistic coefficient for the second bullet based, at least in part, on the first bullet weight and the second bullet weight, wherein the first ballistic coefficient differs from the second ballistic coefficient;
- and providing instructions that indicate different aiming adjustments for firing the first bullet and the second bullet, the different aiming adjustments based, at least in part, on the first and second ballistic coefficients.
