I've killed at least 200 deer with Ballistic Tips and I still use them. Probably the most accurate, or one of the most accurate hunting bullet available. Great lethality if you place the bullet well, and great exit wounds and blood trails if the deer makes it very far. I wouldn't use on on an Elk, but for deer it's just fine. The Accubond is probably better, but it's more expensive and I don't need the upgrade.
I find it hard to believe that you've seen "hundreds of failures" when I've personally had hundreds of successes.
One thing about the Ballistic Tip is that it's probably the most argued about bullet on the market. I can attest that it's a fine bullet and I'll also say that it isn't a magic bullet. Still got to place it where it needs to be to do the job.
