I was fixed a guyfor more than 23 years untill I saw the hole a mech. put in my buddies buck 6 years ago. Since I have changed over to mech I have only had 1 deer die out of sight. But my main reason is every broadhead out there will kill a deer quick when you hit it in the boiler room, But it is when something goes terribly wrong and you make a bad shot that the mech shines with the huge holes you put into the deergives you a better chance that the deer will still bleed out!!
