ideal diameter
2.Methods Based on the theory of hydrodynamics and ammunition, to analyze the influence of the bullet diameter, form, construction, terminal velocity and mass on the tested effects. Results The test results have proved that the small bore bullet possesses the ideal wounding effect. Conclusion Small bore(5 ̄6 mm), higher muzzle velocity (900 ̄1 000 m/s) and small mass (3 ̄4 g) for bullet are the developing direction.
