I find that
When I cast .454s I actually get somewhere between .454 and .4555. I find this is true almost no matter what I am using in the way of metal. I have heard of shrinkage of the balls as they cool down but if this is the case, they seem not to be shrinking to the stamped size of the molds I am using. .451 gives me bullets up to .453 and .457 molds produce up to .458 or perhaps even higher. I am using a tightwad's digital caliper but my measurements with that tool comport with a Starret micrometer.
I think the kit has .451s.
Hope this is not viewed as hijacking the thread.
