Q: I bought a box of Federal ammunition loaded with 165gn Fusion bonded bullets. I was intrigued to read that they are made by using electroplating to form the jacket. Can you tell me how this is done?
I find Fusion bullets hold together to penetrate well and retain a high percentage of their original weight.
A: The Fusion bullet starts with a compression-formed lead core that is then electroplated using a patented process that attaches the jacket to the core, molecule by molecule.
This creates a very uniform coating of jacket material and has the effect of making one solid piece from two very different metals.
Fusion takes bonding to a whole new level since it does not have the core and jacket as two separate pieces ‘soldered’ together by heat after they are assembled.
The bullet is also pre-expanded and formed back into shape in a series of dies to create a pointed, boat-tail bullet.
Federal claims the bullet achieved up to 250 per cent expansion diameter and retained 90 per cent of its weight when tested in 10 per cent ballistic gelatine.
