untalented weapon usage

[Axly Suregrip]

ITL 36 states, "figure who is not skilled with a weapon may still
use it – but he rolls 4 dice to hit, not 3"

but

ITL 115 states, "However, the DX of a figure without the Crossbow talent will be at -4."

ITL 124 states, "Anyone without Guns talent has a -6 to use this."


I believe 115 and 124 references are just the old ITL that did not get updated when they gave us the new rule for untalented weapon use found on ITL 36.

Or, it may be a DX penalty on top of ITL 36 added fourth die to the role.

And if it is just old references, then it does not seem to be enough for the gunpowder weapons since it is DX -6. How do you adjust attack with untalented gunpowder weapon use?

Is this is in an errata?
