Some people love the Barnes product, some do not. I certainly would not call them the "go to" bullet. My experience with them is that they need high impact velocity to be reliable, at least in calibers that are smaller than .338. As to accuracy, some rifles shoot them very well and other rifles will not.

I have shot game with them both in the U.S. and Africa. Most of the time they work great but there is still the occasional bullet that does not open properly or does not penetrate in a straight line. I like them for buffalo in a .375, but have had them not penetrate a warthog and a kudu in a 7mm. Go figure.

Any cartridge that has the bullet so loose in the case neck that it can be spun with fingers is a big problem.
