As I suspect most of you have, I time and time again see the term, "hard cast" used when a person says they wish to buy or cast or use some, "hard cast" bullets.
The term is over used and basically means little to nothing as to one person what is hard may be quite soft to another.
How about some one with the knowledge and or hardness tester come up with a rating system where by we can all KNOW what we and others are talking about.
Maybe 3 - 4 or more categories, soft, medium and hard, each with an established Hardness attached to the term.
The only common really hard alloy, and that used by a limited number of casters when compared to the many who cast with Wheel Weights or alloys of similar hardness, would be linotype.
Guess we could say that bullets cast of linotype are truly, "hard cast" while most other alloys are far softer and NOT truly "hard cast."
I don't have a hardness tester, but seems that it would be a benefit to us all to come to some meaningful criteria buy which we throw out terms such as, the over used and currently meaningless, "hard cast."
Just an Ol'Coot's thoughts, but in the past I have also used "the term" and have come to the realization that in reality, it means nothing as there has apparently been no established rating system by which to say that an alloy is, indeed, HARD.
