Do people think there is some kind of mistake in the stat bloc for these guns? If BC used the DH/DW Scatter rules, they would be pretty good, but as is they seem inferior to bolters in all respects except for the +10% to hit at short ranges.
Was the base damage perhaps meant to be 1d10+9? That would make them better than a bolter at short or point-blank range, but worse at long range (and against armoured targets),and so more balancingout. What do you think?
