What's the deal with sniper rifle range?

[Blasphemous]

I finally got a sniper rifle at level 6. Lo and behold, effective range 60. Wait, what?

Ok, I must have been extremely unlucky with the roll, but just to be sure, let's check the creative menu.

That sniper rifle level 5 I had before - eff range 80 - that was the real deal.

Every sniper rifle at level 6 has AT MOST effective range of 62. That is consistent with level 1, I have generated 3 weapons of each level and the effective range scales properly with each level, until 6, where it drops back to the default for level 1.

Other stats on the rifle seem to be ok and correspond to level 6, except range.

Is this intended behavior? I can't imagine that to be the case, what with there being zero legitimate reason for that.

 

That leaves it being a bug. I'm hoping this is something that can be corrected through config files and so, that is my question:

Where can I find numeric values/random spread for effective range on sniper rifles, relative to the item level?

 

EDIT: Correction - the above is true for every gun in the game...
