Speer Gold Dot. Higher weight retention seems to be MUCH better... The FBI likes bonded bullets, and they pretty much wrote the book on ballistics testing for personal use after the huge incident where their bullets failed to do enough damage, so since they choose bonded, so do I.
I have used a speer Gold Dot .45 in self defense (against a pig... OK, not self defense... I was waiting in a tree lol), and it dropped him to the GROUND in his tracks. Worked great. Expanded just as shown. It is now behind the firearms counter at the Academy in North Richland hills, as well as a Black Talon I put through it just to see how well it would expand.
Personally, I chose to go with Winchester Ranger T-Series. They are essentially the modern day black talons. Just no black coating. And they have dropped enough pigs at my ranch to have me sold. If a 300 pound pig slides to a stop after one of these, I'm pretty sure a BG would at least slow down considerably. (just in case, I keep the whole magazine loaded with them

)
Just my 2 cents...
about 65 days to plastic...
