We designed this bullet for the 44-40 Winchester lever action. Given the sub 2000 fps vel of this cartridge, we decided that a Claw Hammer design would be most effective for hunting. These bullets will be 100% weight retention with the large concave meplat for max energy transfer on impact. The hard hitting design of these bullets will breathe new life into the old lever action. They say this cartridge won the West. We think they would have won faster if they had the Claw Hammer!
