Brian at A Gentleman's Ones has some classic Citadel Chaos dwarves and dwarves for sale. They look great. I like the later Chaos dwarf style too, though I know it's not everyone's favourite, and ideas like the blunderbuss. Interesting weapon in general.
I've statted one up. I used Gotthammer's FireZone, which may be aimed more at sci-fi, but can certainly cope with fantasy, and has plenty of options for weapons. It's a very well-made skirmish game and free to download. I plan to do some sci-fi stats for it too.
The broad blunderbuss is a tough, crude, ranged weapon with a flaring barrel and bore. It is filled through the muzzle with solid shot, whether cast metal or simple scrap, brick or stone. A black powder charge spews the mass a short distance across a wide arc.
Range Acc RoF Dam Type3 / 3" +1 1 5 Jet 9/3, Reload 2
Notes: Range in FireZone is split into bands, with a modifier for each full band out from the firer; the first number is the number of bands and the second the length of each.
The blunderbuss also fires a Jet, and the extra numbers are the dimensions of the cone, a length of 9" and a width of 3" at the broad end. Accuracy here is a small bonus to represent the overall difficulty of missing. The weapon has a Rate of Fire of 1 and not surprisingly a reload is necessary, requiring 2 Action Points, likely to mean about a turn.
I've kept Damage low relative to the sci-fi weapons Gotthammer stats up in the pdf.
I hope I've not missed anything, but if I have, feel free to point it out. If you haven't had a read of FireZone yet, I recommend you do. It's here. Don't forget Brian's dwarves though._
