5.7 x 55.3 (303 case necked down to 22)

This round was given to me as an experiment made during 1942-1943 at the university of Toronto
The name could be : 22-3000
The bullet is galvanized, non magnetic
Hstp : 1942 DIZ

  1. Could you tell me more about it ? Military ? Civilian ?
  2. Is it scarce ?
    Thanks

Yes, your identification is correct, and it was developed on a military contract. It is certainly scarce and is the round I mentioned in my reply to your other .303/.22 question.

Galvanizing is a coating for steel. Non-Magnetic would have to be very high nickle content steel which would not take Galvanizing. ??

You are right it is not steel (non magnetic) but the same color as galvanized steel.
excuse me

Are you certain that it is metal?

Yes John it is metal.
What do you think it can be ??
