One tactic would be to develop several cartridges and use whichever works best.
That would be the way to go if we'd want to find the best one - but we only need one that is good enough.
As such, the choices we'll face next turn are, in my opinion:
1) Calibre
a) small calibre (5.5-6mm)
b) medium calibre (6-7mm)
c) large calibre (7-8mm)
d) very large calibre (about 10mm)
2) Action
a) Bolt-action
b) Semi-automatic
c) Automatic/select-fire
Whether we'll use a 6.5 or 6.6; a 5.45 or a 5.56; a 7.92 or a 7.62 round doesn't really matter in the end.
As such, a few thoughts on the rifles:
Our current revolving rifle should be about 8kg loaded, and be effective out to 1500m. In a minute, you should be able to fire ten to twelve aimed shots.
Assuming we use bolt-action rifles (with a separate, ten-round magazine), the small-calibre variation should be about 2.5kg, effective range of 500m; the medium-calibre 3kg/1000m; the large calibre one 3.5kg/1200m. All of them should be able to fire twenty aimed shots; they should cost at half or less of the RR.
Semi-automatic weapons should be about 25% more expensive, and be able to fire either thirty aimed or about eighty unaimed shots.
An automatic weapon should still be cheaper than the RR, but be almost 75% more weight (with a 30 round magazine). It won't allow you to fire more aimed shots, but about 120 unaimed ones.
Those are all very, very rough numbers, and depend mostly on the rolls we'll make. However, those should give us an idea on what the rifles will look like.
For me, my preference would probably be to make a semi-automatic weapon in a medium calibre, ideally a historical one for more examples and better acceptance. By putting our four talented firearms engineers on that, we should be able to design a pretty good rifle.
Anyways, any thoughts on the engineering assignment/production plan? Anything else needed from us to continue, Aseaheru?
