If I follow your argument, then you seem to be saying, that you are fine with the match-up between cons and grens at range 10, so that cons have a range at which they can do something in the late game, but you do not like that the damage does not fall off between 0 and 10 like any other bolt action rifle.
You are opening a whole different chapter now
Among other things I do point out that having conscripts near range to 10 while other bolt action rifles to 0 is a bad change.
They are a good reference not because they are bolt action but because they mess with weapon profiles curves.
Penals are not a good reference to make your point because they don't have bolt action rifles, they have semi automatic rifles.
Although their weapons are semi automatic they do not follow proper profile being too linear(where their relative advantage should be mid ending up having too much DPS far). This becomes even worse with the ridicules high accuracy bonuses they get.
