Here's a little something I whipped up to output a list of weapon/specimen values to the log. It's meant for the standard weapons however you can add custom to the AdditionalWeapons array.

I've written it to get an accurate set of stats for the official KF wiki so if anyone sees any problems with it, please let me know.

A copy is stored here on the wiki itself.

Code: 
//=============================================================================
// Weapon stat generator	25-October-2012	Benjamin
//
// KNOWN ISSUES
//
//		* Cannot detect where different fire modes share the same
//		ammo (boomstick)
//
//		* Cannot detect penetration for all weapons, must check manually.
//
// ===== INFO
//
// HEAD SHOTS
//
// Every weapon's head shot multiplier is stored in its associated damagetype
// class, except (some of) those weapons whose projectiles implement
// ProcessTouch themselves: CrossbowArrow, M99Bullet CrossbuzzsawBlade. These
// projectiles have their own HeadShotDamageMult variable.
//
// NOTES
//
// (1) Certain classes don't use AmmoPerFire: MP7MAltFire, M7A3MAltFire
// (2) Hardcoded penetration values: Deagle, MK23, 44Magnum, Crossbow, M99,
// and Buzzsaw bow. Look in script files manually for these stats.
// (3) Weapons only have a single ReloadRate stat (none for alt-fire)
// (4) Weapons that auto-reload with a specific time: 
//
//     Hunting shotgun - ReloadCountDown stored in BoomStick.uc
//     M79 - FireRate (fire + reload are same animation)
//     Crossbow - FireRate (fire + reload are same animation)
//     LAW - FireRate (fire + reload are same animation)
//     M99 - FireRate (fire + reload are same animation)
//     Buzzsaw Bow - FireRate (fire + reload are same animation)
