Yes it was a complete pass thru. If you watch carefully behind the fox you'll see dirt and leaves kick up behind it where the pellet hit. At the end of the video the still pictures show the entry and the exit.
I forgot to say I'm shootinf JSB 50 grain pellets in the 860s. I was considering turning the gun's power up to throw them in the mid 900s, but I don't see a need with this kind of performance.
