I have the Alaska Guide Gun by Wild West Guns in Anchorage. It is a JM marked, modified Marlin 1895 in .45-70 Government, and it will stop anything that walks the face of the earth.
Below, find a link to a very interesting read about Vince Lupo's African Safari's, where he took the BIG SIX with a Marlin 1895 .45-70 loaded with Garrett Hammerheads.
