Hello everyone, I am not very well informed about firearms (never fired a gun myself) and I am writing an rpg game system that uses modern fireams. I could use some help with a few concepts. In general, how much damage does a single round from a 9mm pistol compared to a single round from an m16 do? is there a signifigant difference? How wide and how far can shotgun shot be effective against unarmored targets? If a weapon is semi automatic or fully automatic, does firing many rounds increase the chance of hitting a target, and or increase the chance of damaging the target? Can you fire too many rounds and lose effectiveness? If possible, I would like the game to be reasonably realistic. Thank you for any help.
