5.7 x 55.3 (303 case necked down to 22)


#1

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. ??


#5

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