PROBLEM TO BE SOLVED: To provide an in-gun trajectory simulation device, an in-gun trajectory simulation method and a program, allowing reduction of calculation cost, and allowing high-accuracy in-gun trajectory simulation. SOLUTION: In this in-gun trajectory simulation device 1, a division part 101 divides the whole gun inside into a plurality of assumed calculation lattices, and a prediction data calculation part 102 calculates prediction data on the basis of an occupation ratio in each attribute of a substance present inside the divided calculation lattice. A occupation ratio calculation part 13 calculates the occupation ratio in each the attribute of the substance inside the calculation lattice on the basis of the calculated prediction data. The prediction data calculation part 102 and the occupation ratio calculation part 103 of the in-gun trajectory simulation device 1 repeatedly perform the calculation until it is calculated that a bullet moves outside a gun.
