Sorry for the 2nd post, but could you also add "Mono Arrows/Quarrels"? Basically either +2 Pen or Turn Pen to 3, similar cost to manstoppers.
Also, Autocannon shells need a pricing. What about the rarer larger caliber ammo? Tranter .54 rounds (which is based off the .50 AE of the Desert Eagle I presume), should cost more than the ammo size of a stub automatic (which I would estimate as something like .40 S&W, 9mm for Autopistols and prolly 10mm or such for the 1d10+4 pistols). A friend of mine made an incredibly comprehensive real ammo damage scaling for pistols and rifles for a DH homebrew, but that would way too complex to use in any normal way.
A friend asked me to ask these for him:
1. Why are Bolt Shells still so costly?
2. Does the quality of whatever you attach with the melee talent carry over? Such as a BQ mono knife = BQ mono spear?
