Preamble
Mahty is to me the definitive Dwemer modder. Everything mahty releases is awesome, and as such I pay close heed to it. When I got the 2nd Generation Dwemer Gun mod (found here: http://www.nexusmods.com/skyrim/mods/54498/?) I was disappointed that the guns didn't make more use of the J3X weapon scripts. So I made a change to Mahty's file and got permission to share it.

Description
This mod does several things read below to see for each weapon.

Dwemer Gatling Rifle
DMG: 2
S/s: ~100/s AUTOMATIC
Clip: 200

Dwemer Sniper Rifle
DMG: 30
S/s: Standard Crossbow
Clip: 1

Dwemer Aetherium Rifle
DMG: 4
S/s: 3 burst
Clip: 21

Dwemer Aetherium Rifle II
DMG: 4
S/s: 10/s AUTOMATIC
Clip: 30

Dwemer SMG
DMG: 3
S/s: 10/s AUTOMATIC
Clip: 30

Dwemer Assault Rifle
DMG: 4
S/s: 10/s AUTOMATIC
Clip: 30

Dwemer Marksman Rifle
DMG: 10
S/s: 10/s SEMI-AUTOMATIC
Clip: 30

Dwemer Grenade Rifle
Unchanged save name

Dwemer Accelerator
Damage reduced to 25

Ammunition
Normal Bullet, Aetherium Bullet, Sniper Bullet, and Shot Lance have all had their damage reduced.
They make sense being used with these now much more powerful 'guns' but not in standard crossbows.

Installation
Install it with NMM or other mod managers for ease of use.
Or manually drop it in this folder:
C:Program Files (x86)SteamsteamappscommonSkyrimData

It overwrites Mahty's Dwarven rifle 2nd Generation .esp

Requirements
This mod requires Mahty's: Dwarven rifle 2nd Generation
Found here: http://www.nexusmods.com/skyrim/mods/54498/?
And it also requires J3X's: Automatic Crossbows
Found here: http://www.nexusmods.com/skyrim/mods/26329/?

Thanks
J3X for the fantastic Automatic crossbows scripts, both easy to mod and fantastically versatile.
And of course Mahty.
