I've been using them for 2 seasons here in TN. I used to use maxi-balls. I had trouble finding the mb's, so I figured I'd try the pb's. They shot AWESOME! Ragged holes at 100. I got two decent 10 pointers with them but wasn't impressed with the penetration. Shot both twice. Second was my fault, I hit a little too far back(liver). I've seen elsewhere that people have had problems with them fragging but thought I'd ask here since there seems to be more knowledgable shooters.
