#1 parasky Aug 27, 2009 19:47:30	I plan on doing a pre appoctolyptic to post appoctolyptic campaign, but am haveing trouble figureing out gun damage accuretly. I do NOT have any intention of doing... "Assault Rifles do X ammount of damage, Pistols do Y..." ect. Im looking at damage based on caliber, and muzzle velocity (though the Muzzle velocity will be via + #to rolls) Is there anywere that has a well done table for bullet damage based on caliber?

Also, don't get too hung up on it, it is an abstract combat system after all. Besides, people tend to disagree when you try to inject too much realism. Someone will argue that one gun has a smaller caliber, but it will tumble better, or maybe this other gun has better muzzle velocity, etc. Not to say I disagree with what you're doing, I use the d20 Cthulhu tables myself, just don't let yourself get too concerned with "realism".

If your gun does 2d6 damage, you roll two six-sided dice that each have the numbers 1 through six represented on them (one number per side, of course). Rolling the dice typically involves picking them up and deposit them on a reasonably flat surface in such a way that they tumble or "roll" a short distance before coming to rest. Following the example of rolling 2d6, the common way to read the result is to look at the number on the top side of the dice and add up the result. While this method relies on the players ability to properly distinguish the numbers rolled and the ability to add, there really isn't any risk of miscalculating. THe approach is similar for other types of gun damage, e.g. 2d4, 2d8, 2d10 and 2d12 though these obviously use different dice. The d4 can be a bit tricky to read since it doesn't have a "top-side" as such, but this advanced topic really doesn't matter much since most players will avoid using guns that deal this kind of damage. -DF

It does more than just say an M-16 does 2d6 damage, rather it suggests an M-16 with a 5.56 wadcutter does 2d6 damage or an M-16 with a 5.56 armor piercing does 3d6 (no these aren't the actual numbers).  Its a lot of data to sift through, but its a lot of accuracy.
