From it's lore description. You get the impression that it's optimal range is higher than normal, while it's max range is shorter. So it should have a higher optimal range, but it's max should be reduced.
By "lore description" I assume you mean Sarna. It gives a vague description and some numbers on the side that probably don't make sense if you don't play tabletop Battletech.
The thing about tabletop range brackets is that they normally don't mean a reduction in damage with distance. In tabletop you have to roll two six sided dice (2d6) and get a value above a target in order to hit your target. The target is the gunnery skill value of the mechwarrior (4 for a regular mechwarrior) modified by various conditions in the game that make the target higher or lower.
The range brackets of a weapon short/medium/long indicate what modifier is added to your to-hit roll. Short range is +0, Medium Range is +2, and Long Range is +4. So firing a PPC at long range by a regular mechwarrior with no other to-hit modifiers requires a roll of 8 or greater on 2d6. If it hits it still does 10 damage. You cannot fire a PPC at longer than long range, so a PPC will always do 10 damage to any target it can hit.
Now the interesting thing about the Snub-nose PPC is that it's one of very few weapons that does have decreasing damage with range. At short range it does 10 damage, Medium range 8 damage, Long range 5 damage.
So why do weapons in MWO do less damage to targets outside their effective range?
Let's look at the tabletop values for PPC range to get an idea of what's going on:
I'm going to give ranges in meters, tabletop actually uses hexes with each hex being 30m.
Minimum Range: 3 hexes or 90m
(Minimum range in tabletop doesn't work like in MWO. The PPC still does 10 damage inside 90m but at 3 hexes adds +1 to the to-hit roll, 2 hexes is +2, and 1 hex is +3.)
Short Range to 180m
Medium Range to 360m
Long Range to 540m
In tabletop the PPC does 10 damage out to 540m and cannot hit anything beyond 540m.
In MWO the PPC does 10 damage out to 540m, but can continue to hit targets beyond 540m for reduced damage. So we can see that MWO has extended the range of weapons beyond their tabletop values and this is the region where we see damage fall-off.
So let's see what's going on with the snub-nose PPC:
Short Range to 270m (hits for 10 damage)
Medium Range to 390m (hits for 8 damage)
Long Range to 450m (hits for 5 damage)
Notice that the snub-nose actually suffers damage fall-off in tabletop, unlike the regular PPC.
In MWO the optimal range is 270m, exactly the range where the snub-nose does it's full damage in tabletop, and that the maximum range extends out to 630m, so it still benefits from the extended range scale of MWO.
TLDR:
Given how MWO has implemented other weapon systems in the past and how the snub-nose PPC works in tabletop, the current implementation in MWO is exactly what we should expect as a baseline.
The only quibble I have is that the snub-nose should probably benefit from the re-balancing done to the standard PPC and be dropped down to 9.5 heat as well.
