I used muzzy 3 blade 100 grain one time, I shot a doe at 8 feet with one and it didn't even go in all the way, I shot her right behind the right shoulder and I looked for her for 8 hours, no blood or hair. I went and bought some expandables the very same day and shot a doe the next day with them and the deer dropped within 30 yards I had blood spray 5 feet off the ground all over the trees, and I have never lost a deer with expandables.

You can get a three pack of Eastman or Allen expandables for 10 bucks to 20 bucks at Walmart.
