I have a friend who had a Santa Fe. I shot it once and commented that it looked like a cheap knock off of a 1903. I had no idea they were sand castings! Fortunately, that rifle burned up in a house fire. Unfortunately, there were about 20 real milsuprs that went with it. I still have his 2 1911s that were in the fire, sitting in a can of kerosene.

So would a 30-06 field gage by the correct choice to check 1903s with?
