Hi!
This first post is about adjusting the Damage, Penetration and ROF DW stats of Ranged Weapons to the 40k stats. I have also tried to minimize the changes to each weapon.
-----
The below table should help finding approximate damage equivalents:
40K Strength approximate DW Damage (not accounting for tearing, etc)
4 2d10+4
5 2d10+8
6 3d10+5
7 3d10+10
8 4d10+7
9 6d10+10, maybe 5d10+10
Pen conversion: DW Penetration is approx 2x(7-AP)
ROF conversion: DW ROF is approx 2x(40K ROF) (Rapid Fire could be considered a 40K ROF of 1.5)
-----
With these rough guidelines in mind, I would suggest the following changes:
Astartes Ranged:
Plasma Gun: add d10 damage
Meltagun: add d10 damage
Heavy Bolter: damage 2d10+8, ROF 6 (to make the Assault Cannon better in comparison)
Boltgun: damage 2d10+4 (keeping a greater distance to the Heavy Bolter damage)
--
Tyranids Ranged:
Barbed Strangler: add d10 damage
Stranglethorn Cannon: add 2d10 damage (btw, this has to be a typo - the SC needs to have a d10 or so more than the BS)
Deathspitter: add d10 damage, add storm quality (or double ROF)
Devourer: add 1d10 damage, reduce ROF to 4 (or strip storm quality)
Fleshborer: add d10 damage
Heavy Venom Cannon: add d10 damage
(NOTE: some of this this might make hordes too deadly - GM might consider adding
d10 less than suggested for hordes with special exemplars (independent beings
who are not part of the horde wrt game mechanics) gaining the full damage
bonus.

Tau Ranged:
Plasma Rifle: make Pen 10, perhaps ROF3
Missile Pod: add d10 damage (perhaps 2d10), make ROF 4
Burst Cannon: add d10 damage , make ROF 6
Pulse Weapons: add d10 damage
(NOTE: see note on Tyranid weapons. Also: some of the Tau weapons are not only a
bit underpowered they also have no tearing unlike the bolter. This might justify
giving them the additional d10.)
Any thoughts? What to do with the Assault Cannon under this configuration?

) simply because Damage Type of Rending, at least in my experience, is already confusing enough - people seem to forget it equates to a damage type/class rather than a special weapon quality (usually they equate it with tearing).
