The 295 gr Powerbelts shoot the most accurate of anything I have tried in my Optima Pro, and over a pretty wide range of powder charge (777), but I had less than desirable performance on the two does that I shot with them a couple of years ago. I found them both, but there was absolutely zero blood trail (both shot in the heart / lungs at less than 50 yards - no exit wound). One took off across an open field and fell after about 175 yards in the open, and one I shot on an open mature hardwood hillside and I watched her go down about 125 yards from where she was shot. As with all deer I shoot, even when I know exactly where they fall, I practice my trailing skills by locating where they were shot and looking for sign. I probably would have found them both eventually if it was brushy, but I just don't have confidence in being able to get a decent blood trail for tracking with those Powerbelts. I shoot XTPs now and had good results with the one deer that I shot last year - hopefully I will get a chance to get another data point or two this weekend!
