From FM 23-71, July 1964 which is the version of Trainfire you qualified under, you needed the following scores:

Possible: 84

Expert 51 to 84
Sharpshooter: 40 to 50
Marksman: 27 to 39

back then you fired out to 350 M with the M14icon in basic, whereas when revised after 1974 the course max was reduced to 300 M with only 40 shots.

On the pistol I could not find the standard in 1969, but in 1940/41 the possible was 765 with 85 shots of which the highest value was a 9. You likely fired on that course of fire, though once again I cannot fined the actual classes of scores.

got that information out of FM 23-45

Hope that helps
