Two Cavity Mould Question

[caseyboy]

Is there any problem with casting using only one cavity from a two cavity mould? Was thinking of removing the GC shank from one, then only casting what I needed from the appropiate cavity.

It is done all the time,just make sure the mould is heated right then you should have no problems.

Nope, usually you get better accuracy (less deviation) by using only one cavity.

Nothing wrong with that at all. In fact, with small blocks and large cavities such as the 500 grain .45s, you get better, more filled out bullets and it's even possible if your have metal working facilities to make sprue plates to cover the unused cavity to make things neater./beagle

I've done it many times. Just keep the pace up so the mould stays hot enough.

Do Note that your production will go down fully 50% by using only 1 of two cavities. :groner:

For years I used double cavity molds--then I bought two used single cavity..I expected the worst: slow production...but I kept track and found that my production rate was much more that 50% when using a dual cavity vs a single. Seems that I had less cool down time with one.

With a dual cavity the first cast freezes faster than the second...so you have to wait a bit for it to freeze. With a single cavity you can adjust the melt temperature to get an quicker freeze rate, so your production rate increases. You cannot do so with a dual cavity as the mold will not fill right.

Thanks guys. Just what I figured, just wanted to pass it by the "knowledge pool".
