Whenever I have to "take out" a Gorilla my preferred "rig" is a Western Star logging truck or a Heavy Kenworth oil patch "sow".
....speeds in the range of 60 mph seem to do the trick, all this higher velocity stuff is just hot air.

Busy here this time of year, and I left this hanging,....maybe giving the impression that the idea is to SQUASH Gorillas, with heavy trucks.
The way this actually works is that one hangs a nice 30 ton Crosby snatch block of of his headache rack's little jib crane,....and basically does a "Drive by head shot",.....
No muss, fuss, or bother,....paint scratched, blood, guts or brains on your "rig".
As noted,...anywhere's from 55 to 65 MPH will let the block swing out tangentally in an arc, handsomely, and effectively, "Bonking" the offending Simian.
We put over ripe watermelons on posts, by way of practice targets....
Good practice drill, for the REAL thing.
Just be careful that none of these, "10 ton blocks at 80 MPH" types delude you,....slow and heavier WORKS.
