An old gun...

[Krensky]

Something I put together to support a Napoleonic War game I've been weedled into running for my players.  I'd like some feedback and any suggestions.  I have no idea what caliber or cost to stick these at... partly as they'll be used by me in in the 1800s and I wasn't planning on using the Gear system.

Pattern 1800 Infantry Rifle (Baker Rifle)
4d4+2   1-2/19-20 1S60  12  80ft  S/2h  FLK,NUL(0),SLD(6),UPG(Bayonet Lug, Leaf Sight)  9lb   -  15/+0 1800

Land Pattern Musket (Brown Bess)
4d4+2   1-2/19-20 1S60  12  10ft  S/2h  FLK,IMP,INA(4),NUL(0),SLD(5),UPG(Bayonet Lug)  10lb   -  15/+0 1722

Pennsylvania (or Kentucky) Long Rifle
4d4+2   1-2/19-20 1S40  12  80ft  S/2h  FLK,NUL(0),SLD(6)  10lb   -  15/+0 1740s

This is REALLY rough, not much more then what came off the top of my head so I'll take any comments and suggestions.

Fire-lock (FLK)
This weapon does not use modern cased or caseless ammunition, insteady it is loaded with loose powder which is ignited by means of a flame or spark generated by a fuse, match, flint-lock, or percussion cap.  This makes the weapon susceptible to atmospheric moisture.  Note these modifiers by themselves will never allow a level 4 critical miss.

• Very Humid (also ocean spray and fog): +1 error range,
• Light Rain: +2 error range
• Moderate Rain: +3 error range
• Heavy Rain: +4 error range,
• Storm: +6 error range
• Hurricane/Blizzard: +8 error range

The other things I know I need is a way to squeeze longer range out of a round by using measure loose powder and some way of modeling the smoke put out by these things.  The measured powder can probably be replicated by a feat or skill check and an extra action to add a bonus to attack, but I'm not sure about the smoke.

You might model the smoke providing some sort of concealment bonus to Defense.

You might also consider the hot-load rules in the weapons section for ideas on extra range and/or damage.

[Krensky]

My main thought on the smoke of a black powder battlefield was to hash out something where every X shots adds a +1 concealment to defense for everyone and every Y (where is something like 2X) shots treat invoke some sort of noxious gas environmental hazard.  The later I'm not QUITE sure on since the players in question can't decide if they want this gritty and realistic or heroically cinematic.

I looked at the hot load rules, but they aren't quite what I was looking for, but looking the ammo descriptions over, the effect I want is the same as the match grade ammo, so I'll just lift those rules.
