[QUOTE="Veteran, post: 2443913, member: 118038"] Thats why Haral built a finite element model, which has a barrel with an almost infinite number of cells (you can tell the model to make millions of cells and time steps as it calculates the pressures, sound waves, frequencies, friction, etc. cell to cell as the bullet goes down the barrel), and you can repeat the experiment as many times as you want and never change the answer unless you change the model inputs. Im sure he trued his model or history matched it to actual data to start with. This is the same way, Oil companies study and predict fluid flow through porous media, ie rock, its the same way we model rocket ballistics and flight, and the same way engineers fugure out structural loads and deformation and materials failure problems. They build very detailed cell to cell models which calculate events from a starting point and endpoint at one cell becomes the start point of the next cell and at the end of the model, one gets a resulting set of final conditions.
