Introduction
I have researched and compiled this supplement in a effort to introduce historically accurate firearms into the AD&D, Mask of the Red Death game setting. This supplement should satisfy all anal people like myself who appreicate firearms and their evolution. The idea of 'Range Class' as far as I know was developed by Brian J. Maloney in his 1995 article 'Medieval Firearms for AD&D' and has been adopted, giving proper credit, for use in this supplement.

Terms Discription
Range Class: an abstraction of the accuracy of a gun over various distances. Each firearm has a Range Class listed on the FireArms Table. The following table translates Range Class into AD&D modifiers.

Range Class	To Hit Modifier
	+3	+0	-2	-5	-10	-20
1	10	30	50	80	110	150
2	15	40	60	100	160	200
3	20	60	100	180	300	375
4	25	100	250	400	600	1200
5	30	180	600	900	1200	3000
6	35	300	1200	1800	3000	6000

All ranges listed above are in feet.

S,M,L: a rough translation of AD&D ranges corresponding to the Range Class Table.
ROF: the rate of fire for the firearm given as maximum shots fired per round.
Shots: the total number of rounds or shots the weapon will hold before reloading.
Reload: the number of rounds it takes to reload the firearm.
Speed Factor: the AD&D modifier to inititive for the firearm.
Wt: the weight in pounds of the firearm.

Damage By Caliber
A simple method for determining damage is to assign damage based on the size and force (stopping power) of the projectile. This is listed below on the Damage Table. Knockdown is per current AD&D rules.

Caliber of firearm	Damage	Knockdown
.10 to .20	1d4	1d4
.21 to .30	1d6	1d4+1
.31 to .40	1d8	1d6
.41 to .50	1d10	1d6+1
.51 to .60	1d12	1d8
.61 to .70	2d6+2	1d8+1
.71 to .80	2d8	1d10
.81 to .90	2d8+2	1d10+1
.91 to 1.0	2d10	1d12
1.01 to 1.10	2d10+2	1d12+1
1.11 to 1.20	2d12	1d12+2

Shotgun Damage By Size
This table list damage for shotguns and firearms that fire 'shotgun like' shot. The number of hits column represents the actual number of shot hits. Useful for Stoneskins and the like.

	Shot Size		Damage		No. of Hits		Knockdown
        Small Shot              2d4             2d8                     1d2
        Buck Shot               2d8             2d4 			1d10
        Slug                    2d12+2          1                       1d12+2

There is a 30% chance of no fire in light moisture conditions, a 60% chance in moderate moisture conditions, and a 99% chance in heavy moisture conditions (total submersion). These conditions are determined by the DM.
