You might want to rethink what you're shooting Devil. Looking at your target I see some of your bullets seem to be leaving a piece of plastic over the bullet hole and sealing it up. That's really going to screw up your blood trails.

Good shooting.

I wonder if dipping the back half of the bullet in Lee's Liquid Alox and letting it dry would allow you to hunt on a clean barrel without worry about the bullet moving off the powder.
