The Joy of Guns – Part 3

In the last article we made some design decisions about firearm accuracy and tied muzzle energy to damage dice based on Dr. Wilson’s study on gunshot wounds.

You can follow all of the design choices by clicking the links below:

Next, we’re going to handle weapon ranges and reloading time for guns in Dungeons and Dragons Fourth Edition.

Adding Guns to Your 4E D&D Game

Effective Ranges for Firearms

Rifles at close range in a withering rain of bullets

Single projectiles behave differently than scatter-shot ammunition like the kind used in a blunderbuss or shotgun.  With that in mind we’ll break them into two groups.

Bullet ranges tied to firearm types

  • Black-powder pistol = 10/20
  • Modern pistol = 15/30
  • Black-powder smooth-bore long arm = 15/30
  • Black-powder rifled long arm = 25/50
  • Modern rifled long arm = 50/100
  • We can extend ranges with feats and items later

Scatter-shot ranges tied to firearm types

Scatter-shot fired from a blunderbuss or shotgun will be simplified as a blast.

  • Blackpowder shotgun = close blast 2
  • Modern shotgun = 5/10, blast 2

Reloading Times

Reloading quickly can be important.

Here is a breakdown of the design decisions for reloading times:

  • Black-powder weapons – reload short rest (We can use feats to improve this later)
  • Modern revolver – reload move action for 2 bullets (We can add the quick-loader as an item later)
  • Magazine loaded weapon – reload minor action
  • Belt feed weapon – reload standard action
  • Rifle – reload standard action (chambering bullet is free action)

Weapon Tables

This is a draft of how the guns would look in the weapons table.  We still need some additional information before we can assign cost to each of them.  (All weapon weights are rounded down.)

RANGED BALLISTIC WEAPONS
Handguns
Weapon Prof Damage Range Price Weight Group Properties
Flintlock Pistol +1 2d4 10/20 X gp 2 lb. Ballistic 1-shot, Load Short Rest, High crit
Webley Revolver +2 2d4 15/30 X gp 2 lb. Ballistic 6-shot, Load Move (2), High crit
Makarov Pistol +2 2d4 15/30 X gp 1 lb. Ballistic 8-shot, Load Minor, High crit
Beretta 92 +2 2d6 15/30 X gp 2 lb. Ballistic 10-shot, Load Minor, High crit
Long Arms
Weapon Prof Damage Range Price Weight Group Properties
Flintlock Musket +2 3d6 15/30 X gp 10 lb. Ballistic 1-shot, Load Short Rest, High crit
Thompson Machinegun +3 3d4 50/100 X gp 10 lb. Ballistic 20-shot, Load Minor, High crit
7.62mm AK-47 +3 4d6 50/100 X gp 9 lb. Ballistic 10-shot, Load Minor, High crit
Remington 700 +3 4d8 50/100 X gp 6 lb. Ballistic 5-shot, Load Standard, High crit

We will continue adding guns to this table but, in addition, each weapon should still get its own magic item description which we can use to add additional effects, level, cost, and even magical properties if we like.  We will also create firearm related items, feats, and perhaps even some powers specifically for firearms.
