    Anyone know what this is. I have the picture, NOT the mould. Also, can’t remember now why I saved it.

    Lyman 457661/510gr
    specifically tailored for Black Powder Silhouette (BP SIL) and long-range target shooting, where the high
    ballistic coefficient of a 510-grain bullet provides better stability at distances exceeding 500 yards.

    That's neat, I've never seen one. I'd love to have samples of one of those!

    Thanks! I have no idea why I have the picture saved. May have had a project in mind some years ago.
