Step into the woven shoes of our most primitive ancestors, patiently waiting atop a cliff face determined to bring back a moose for your ice age family. Lob a fat rock at the nearest endangered megafauna, absolutely obliterating any potential for a trophy, and also every other part of the animal, and return to your roots. Those cap-lock-main try hards will never recover. This is hunting the way God intended it.
Three calibers, river pebble (with sling), rock (with slingshot) and boulder (boulder).
