This Coastal South Carolina buck gave me a 15 yard broadside shot and the Jak-knife certainly performed well. The broadhead busted through two ribs, gave me a pass through and the buck only ran 40 yards before piling up. Couldn't be happier with the results. I took another buck and a big doe earlier this season (both of which were pass throughs and neither ran over 50 yards.) This is a great broadhead along with the jak-hammer.
