Federal Ammunition
Indeed, Federal is loading this bullet and has also modified it with a polymer tip and now has added the Trophy Bonded Tip to its lineup. However the TBBC is still available in their Cape Shock line for large and dangerous game. Furthermore, I've read that the original Jack Carter design using copper has been revised with the use of guilding material an easier alloy to manufacture for it is more maleable and easier to clean off the machinery. The Barnes bullet is a fine one too, but the velocity window for best upset, is limited; too fast and the petals sheer off; too slow and the bud is barely opening. Great penetration but loosy enegy transfer at both ends of the spectrum. So, my question still remains to be answered.
