Shot a deer with the Rage 2-blade last year. It was a 10 yard shot and the deer didn't make it 50yds. The entry and exit holes were huge. No tuning was necessary. They fly just like my field tips. My only complaint is that it doesn't take much tension for the blades to open. A couple times last year I bumped a small branch with the arrow and the blades came out of place. The practice broadhead is an added bonus!
