    That does look promising. Is the Roto158-190F alloy the best for this purpose -- where best is defined as providing the most precise, constant-density, void-filling casting, as well as the ease of...

    Water has surface tension, which can trap tiny bubbles. Could get around that by using a surfactant, but then there's still the problem of how to plug the barrels to a precise point.

    So far Pb2au...

    Very clever! Should probably use cutting fluid or some other non-wetting fluid to avoid the problems associated with surface tension, like tiny air bubbles inside the bore.

    Good ideas on the fluid! In this case I need to be able to plug the bore at a very precise depth.

    So let's assuming I'm going to be measuring water-soluble cutting fluid into the muzzle. What...

    I don't think the temperature variations in my workroom are a problem.

    I guess I could try to use a ball slug and see if I can calculate a difference with a micrometer based on the land diameter,...

    From a traditional ball slug I don't believe I can measure groove width and depth to enough precision. These are all 5-land .308 barrels. I am expecting cross section variance to be third order at...

    Using lead to measure barrel volume

    In order to test a hypothesis I need to very precisely determine the (relative) volume/length of a few .30" barrels. The barrels are a mix of stainless, 4140, and nitrided 4140 steels.

    The best...
