Just maybe H205 and Norma 205 had more in common than the number. Certainly each was promptly discontinued but at the time I never heard that they were actually the same though they may have been. I thought H205 was an attempt at a knockoff by another maker to cash in on the enthusiasm and just possibly again there was a golden lot but too much variation to leave in the lineup.
In any event Norma 205 was popular enough and people were excited enough about Norma 205 that many people reported results. FREX Rifle Issue 108 - November, 1986 reports results in the .257 Roberts AI. Load Data with its search by maker and by powder has a vast number of loads reported in a great many cartridges
