Cheezy Merga Wraith?
For two months I was hoarding all the ammo available for my first epic battle (60 rifle rounds, 50 shotgun rounds ~ 100 handgun rounds), but surprisingly for me, mr. MR kicked the bucket after one rifle unload and three shotgun unloads, the last one, applied to "weakened" creature killed it . Well, that was easy: run-shoot-run for several times and voila! the thing is destroyed.
