Ihave to agree that the blood trail is minimal with the power belts. I also attribute that to the fact that I can' t seem to get one to pass through! I don' t know how you guys are getting pass through shots. I hunt with a couple of others and we have shot deer with everything from 80grains to 150 grains at yardages of 20 to 100 yards and to date we have not been able to get one shot completely through the deer. Almost every time we have found the bullet just under the hide on the other side. Perfect expansion with complete energy release. I myself am impressed with there preformance and acuracy, but not the price. Most deer I shoot with them don' t go that far so the blood trail issue has not been to big an issue with me. However if I was to go Elk hunting or other larger game I think I would go back to a maxi ball for that hunt. Just my $.02
