You know, there is a reason I buy as many Fusion bullets as possible on Gunbroker or Midway USA closeouts - they to me represent THE best bang for the buck in terms of performance in .308 caliber or higher.
I specify the 308 or higher, because I did experience a bullet failure in 6.5 Grendel and I don't have enough time in with the smaller calibers to say whether it was a fluke or not....
Here are some photos of .338 (1 bullet) and .308 Speer Deep Curl recovered bullets.
Note: The Deep Curl is similar in design and construction and predated Federal's Fusion but like someone else mentioned Speer's GoldDots are similar as well - so the best way to know for certain is to recover as many bullets as possible to make a final determination.
