You got me thinking of the only one I lost with those power belts. About 10 years ago I shot one while making a rub right at dark the smoke just went nowhere and there was no blood and couldn't find him. Really excited to try these new bullets out.I killed a truckload of deer with Powerbelts. They load easy, shoot straight and the deer usually died within sight. But I am wise enough to know eventually you get a tough deer that runs off and with no blood trail you may or may not find it. That's why I changed to Expanders. Stevie Wonder can blood trail deer shot with them.
