Range limit on kill credit

[srmalloy]

I have discovered that it's possible to be too effective in building for separation between you and your target. I took my AR/EM Blaster out to Terra Volta to work on the defeat badge for Sky Skiffs, and after shooting more than three dozen of them out of the sky, my defeat total on the badge stands at... nine. This appears to be an artifact of my hunting them at extreme range. Sniper Rifle, with a full set of Superior Blaster's Wrath, claims to have a range of 180 feet; I don't know whether this includes the 10% bonus from Superior Blaster's Wrath. Boost Range gives me another 59%. When I shoot a Sky Skiff using just Snipe, the defeat count credits; if I'm far enouogh away that Boost Range needs to be active, the defeat count does not increment, no matter how many Sky Skiffs I put down at extended range.
