Cayugad, I took a big doe last season using the barnes expanders with a double lung hit and she still went a good distance before going down. Entry and exit wounds were the same size, about the size of a penny. When I was sighting in, I was shooting into a 3/4 inch piece of plywood with a paper target on it and a huge sandpile behind it. My buddy dug the expanders out of the sand and it looked like you could stick it back into the sabot and shoot it again. They are very accurate, but I was not happy with the results. I have seen people using the powerbelts on the outdoor channel and they seem easy to load. The expanders where very hard to load even on a clean barrel. Hope this helps and thanks for the replies all.
