The 6mm 55g varmageddon at 3590 fps will decimate a coyote at 40 feet as I found out yesterday.
He was a very heavy furred coyote that just would not stop flying into the call when barking at it, crud I though it was going to nip me!
I was bummed at the damage since the under belly was completely missing, but being so close it was unavoidable...unless I let it got & that aint going to happen.
