Semisane, I have killed a couple with the .457-405F sized to .451 . They work great but I've only recovered one. Mine come out of the mold at 421 to 423 grains.

This one crashed through the rib cage of a medium sized buck and lost about 50 grains weight before lodging just under the skin on the off side.I believe the bullet weighed 373 grains as shown.

Not bad on paper either



One of my 340s all dressed up and sized to .451


and those do quite well from a 30" twist Knight
