I once shot a shoat and it flipped backwards... does that count?
Pacomdiver: I did look into the 458 socom and it does interest me, however if the round doesn't take off how would I get more brass. There isn't much on the shelves now of course, but even when fully stocked I haven't seen 458 Socom ammo out here in the sticks. That is my concern with the 450 Marlin too. I have decided to go wildcat and have the gun built as a 458x2 American (will actually be a little longer, I think a 450 Marlin reamer will be used but stopped short to allow the use of standard belted brass.) At least with this wildcat I could probably find all the brass I'd ever need under deer blinds.
