History has long said the 30-06 Martini used in the 1920 US Olympic shooting team was a Hartman Hammerli Martini in standard 30-06.

I just now found a Video that may change that historical fact to myth-maybe.

Morris Fisher shot the Hartman-Hammerli-Martini so badly, that at the last minute he switched to the 03 Springfield in 30-06 and won the Olympic medal in Free rifle.

I did not find what cartridge Morris Fishers Martini was chambered in. I am going to call the NRA Museum later this morning and see if I can find out.
