That is cool. Never hunted turtles, but hunt Water Snakes. Largest I have killed was 5 feet long and about 1 inch and half thick. Very tasty meat. Kiled it with my slingshot, it was basking on log 14 feet out of lake shore, i set a rock in the ppouch and nicked it in the back, I broke it's spinal cord. had to pull it ashore with stick. Finaly chopped its head off with my hacthet.
