Don't have a TC, but powerbelts were very accurate in my 1-48 Cabela Blueridge (Pedersoli) over 80 grains Goex. I've never used them deer hunting as I didn't like their terminal performance in wet phone books. But as bigblock reported below, many people do find them perfectly acceptable as deer bullets. I suspect the heavier weight powerbelts probably hold together and penetrate better than the lighter ones.
