That's a fair question...from what I recall someone with a penetrator and onyx bolts (139P) was one hitting them. The big shot with gold bolts has 145p and a faster projectile speed (80 vs 75) so that'll add to it's damage also.
However I can't 'confirm' this for you, I'm a week or so away from being able to afford the bigshot, so I can't give you anything concrete till then.
EDIT
I can confirm for you that penetrator with onyx bolts can't one shot rangers on ragnarok, so I'm beginning to doubt the bigshots ability to one hit things on ragnarok, unless the additional 5 missile speed and 6p (If using gold bolts which most will be) will give it that extra punch.
