Years ago I molded some 148g hollow base wad cutters. I used wheel weights with no added antimony or tin, at 1000 fps. It made me chuckle when I smacked. a raccoon for the first time. It sounded like you had hit a 50lb sack of flower with a 2x4 as hard as you could. Much like the coyote I plugged in the back yard 20 minutes ago with a subsonic 190g Sub-X out of my 308.
