Great to see all the focus on the original Monolithic bullet here! As always Ron amazes with work, detail, accuracy and photographic skills. The 458WM T has always been a great choice for Cast shooting. We have exposed the Truth of that over the last couple of years along with all the other Myths Busted. Thank you Ron for pointing out the heat treatment results versus Aging data. Lot easier to let them lay in the bullet drawer than heat treat them. I do think that the presence or lack there of for the two elements, Antimony and Arsenic, play a role in Heat treating. I don't see any reason to explore that except for the cause of science because if we can get to 20 + BHN with 95-2-1 alloy, we simply need nothing better for a hunting bullet.
