I am aware that bullet as-cast size with vary depending on the type of alloy used to cast the given bullet. But I'm envisioning something in the range of 0.0005 to maybe a maximum of 0.002 inch variance
I did a search here and found nothing. I'm headed to the web next for a broader search. But does anyone have a rule of thumb for alloy hardness vs as-cast size?
UPDATE: I hit Submit and then did a search on the web. Found many answers, most of which were vague. One was a reference to a page on the CBA site, but the link failed to find the page. However, on that other cast bullet site, I found a post where someone actually posted numbers. It seems antimony is the primary culprit in making bullets grow. Nobody said this, but that leads one to believe that in the absence of antimony hardness differences do not result in size differences. I'm talking phyical dimensions of primarily diameter here and not weight, which could be altered by alloy density. I'm also feeling a bit proud in that my guesstimate at how much a bullet might be able to expand lined right up with the reply from a member named Shiloh (for those who might know him. I don't). He actually said "0.0005 to 0.001 inch with a max of about 0.002 inch for increase in antimony.".
So, this also makes me think that the comments I hear from others that harder bullets tend to be bigger is not 100% true if that hardness is driven by adding tin and there being no antimony in the alloy. That's kinda of a question more than a statement.
Thanks.
