The Federal Fusion bullet is built by eloctroplating a lead bullet with copper according to info I got from Federal. Similar to the way jewelry gets electroplated with silver or gold.
I'm told the Full Curl bullets are swaged. The jacket is the same thickness the full length. I did get that from them. Price is what is getting my attention. Cheaper than most non-bonded bullets. And if they're accurate, might be a good choice for paper targets and thin skinned game. They'd work on larger game also but I prefer the thicker jacketed bullets like Trophy Bonded Bear Claws and Swift Scirrocos. I've had great success with these two bullets.
Federal's new Trophy Bonded Tip bullet might be a great bullet if it's ever available to handloaders.
