Well some peoloe have experienced failures with the partition,even though you haven't.
What some folks may call a failure others won't... Of course this can be said for all bullets, and that's why there's so many differing opinions here...
I've never had a partition fail to do what the maker said it would do, but i have had "three" partitions that i can remember, thatdidn't pass through...Does that mean they failed???
I like my bullets to exit, but i wouldn't say those threepartitions failed... All three of them broke a lot of heavy bone and still gave good penetration...
