    Bullets not casting properly

    I have a custom aluminum 4 Cavity mold, made by Accurate Molds. 32 Cal. 60 grains SWC
    i an getting a line around 3 sides of the bullet. At first I thought it was indented, I contacted Accurate Molds and got a very short reply that I was not casting properly and the lead was not filling out properly.
    this was the same on all 4 cavities.
    I get this line, at temperatures from 650-1,000 F. It also hapens at all lead types from pure to very hard foundry lead. I have casted lead for many years with no problem.
    after a very careful inspection of the bullets, it is not an indentation, but a very slight out filling.
    when I size the bullet thru a die the 2 sides below the nose are pushed in, and the line on top gets pushed in when the top punch pushes the bullet in the die.
    but I am left with a line on 2 sides of the nose.
    is there something I am doing wrong, or is the mold at fault.
    thanks in advance.

    Some pictures would be helpful if you can post them too.

    Are you talking about finning? Can you post pictures? That may help us see what you are talking about.

    Check to see if the mold is closing right. There could be a small spot of lead or a burr making it hang up. If it is OK, are you casting too hot?

    the accurate molds are a bit temp sensitive.
    the ones I have will cast best at temps lower than other aluminum molds.

    I'm having a hard time picturing what the OP is saying about three lines, unless it's some light finning.

    My thoughts are there may be an alighnment issue with the blocks or a slight bevel around the cavity causing this. My question is are all 4 cavities off the same and the same exact defect? If so a slight pin adjustment may cure it.

    As you can see I get sharp edges. The bullet casts very shiny.

    If the three sides your talking about are the 2 sides and the top being no.3.
    Isn't that just the parting line? Otherwise i'm still lost on the 3 side thing.

    I would check and make sure that the mold is closing properly.
    From the picture I will guess that there is an alignment issue.

    All 4 cavities are the same, yet the mold seems to align properly.

    Wow - blowing it up, it looks like alignment to me, with the two halves off by a couple thousandths.

    I agree...Blow the pic up and look at the shadow at the base. you can see the misalignment in the shadow

    Alignment issue. Ensure your mold and alloy are up to temp. Maybe a light tap of the mould blocks on the bench prior to pouring. I'd expect bullets like that from a Lee, not a premium mould.

    Tripod not necessary.

    have you lubed the alignment pins?
    your only off a tiny little bit.
    how do the bases look?
    is one side is a bit lower than the other.
    or is one side of the mold shifted further forward?
    all of these things are alignment pin related, and it could be something as small as a burr around a pins base or in the hole, or one pin is in/out a bit more than the others.
    it could be something as simple as the mold needs some use for the parts to wear in to each other too.
