Yep
Power wise, you have plenty.
Sighted in as you are, do what Ridge Runner says.
If this is a common scenario for your hunting, I'd bump that zero up to 3" high at 100, then you'd be just about 3" high at 200, and only 3" low at 300, assuming about 3,000 fps. Then if he steps out at 300 or less, center the chest with the crosshairs and squeeze. Practice enough so you know you can do it.
