Ideal 490 Double Cavity Mold

[BP Addict]

I ran some 50 cal balls over the past few days. I know from reading Dutch Schoultz's material that double cavity molds can throw balls with differing weights. I was expecting two but ended up with three!


They came out 177 grains plus, 178 plus, and 179 plus with the majority being 178. I know part of the extra weight is the sprue. The lead was sheeting from an X-ray room. I was told that it was pure.


Has anyone else experienced this?


Thanks!

Walt


P.S.: For better accuracy, I separated and boxed them by weight. That way there won’t be a BIG discrepancy while shooting.

I have but they shoot plenty well enough for me. I don't separate them based on weight.

I'm paper Target Shooting so am trying to keep the variables down.

If it were steel such as gongs or clangers, not so much.

Thanks!

Even single cavity moulds will produce varying weights. Unless you are a very serious paper 'X' hunter, those tiny weight differences are of no consequence. That said, yes, two cavity moulds can produce different results. Personally, I stay with single cavity moulds because they are lighter to handle, heat quicker and more evenly and, I have found, can produce as many balls in a give period of time as the double cavity ones because a good working rhythm is much easier with them.

I also prefer the single cavity molds. I find that I can get more "good" balls in an hour with the single cavity mold than with a multicavity mold. With my single cavity mold I have almost no rejects after the first five that "warm up" the mold.
