Munitions Testing

Prototype X, granting the 'Expanding Shot' ability, seems to make this quest impossible to solve (at level 50 currently, with Legion content scaled to 45). I one-shot every creature, and get no credit for any of them. Tried taking off all my gear, but this doesn't seem to affect the ability's damage dealt.

Ok, this is a bit of a wonky one when you're redoing old content as a high level toon.

The problem is that you don't get credit for killing the animals because you oneshot them with your goblin gun from the rack.

What's supposed to happen is that you target a wolf, click the button in the middle then a beam comes out, and enlargens the animal with a progress bar at the bottom of your screen, then once the animal is sufficiently large, you have to kill the animal. So, how do you do this?

Good ol' [item=97919]. Which if, if you're like me and an Alliance main, you never got around to getting, but it's actually quite easy if you check it out (i always thought it was going to be a slog to get, all i needed was a low level Horde alt that i put into legion chromie time, look it up, it's easy).

TLDR:
-Get the "Whole Body Shrinka" toy,
-speak to [npc=99468]
-interact with [object=246975]
-position yourself into a location where there are 10 wolves close by (once you are shrunk, you are REALLY slow), somewhere around 55.7, 54.3 is a decent place, and work your way to 56.0, 55.2
-Shrink yourself,
-target one of the wolves that are highlighted.
-press the button on your screen,
-wait a second or two until the wolf is enlarged and has a greenish tinge
-single target kill that one wolf, (no AOE)
-rinse and repeat for 10 wolves.

The whole body shrinka is like a 3 min duration (with a 30min cooldown) and i sorta stuffed around for the first bit and didn't pick a good position the first time i did this, and only just got all 10 by the skin of my teeth, so if you're careful with where you are positioned when you activate it, you should have ample time.

I have found a solution to this. Use Whole-Body Shrinka' apply the debuff to a mob with the Prototype X, then use Soft Foam Sword to one shot the mob. It only needs one tick of the debuff from the prototype weapon to work, but you can fully channel if you feel like it with the Whole-Body Shrinka' buff on.
