Although the Buckshot does slightly less damage per second, it is far more energy efficient. Considering the above values, and that the Magma Hammer Mk IV only fires at 66.67% of the speed of the Buckshot, we're still better off using Buckshots as our staple hull weapon. Further, the speed of the Magma Hammer Mk IV is 500, to the 750 of the Imp. Debilitator, which will throw off the targeting reticule for those of you who use it.
The only alternative I could suggest would be codenames, but the power drain and the refire makes them horrific. However, if you're using Magma Hammer Mk IVs as it is, you might be better off with the codenames. But, those are on a last resort sort of order, if I understand correctly.
All that to say, we do need a better hull crushing weapon, as the Buckshot isn't quite up to par with that contraband nomad equipment that our enemies seem to use.
