Roger,

Try our own CBE moulds in Australia, Jim Allison does a copy of the "Paradox" style cotton reel type bullet. It comes with both a hollow point pin and a solid pin.
From my lead, the hollow point weight 680 grains and the solid 730 grains.

Also NEI in Texas make a couple of designs.

And the maker I have not long found, and have ordered a mould from him, but haven't received it yet is Accurate Moulds in the USA.

If you want a round ball mould in 1 thou increments, try Jeff Tanner in the UK.

I'm travelling with work at the moment, but can post photos of the CBE and one of the NEI moulds when I get home if you like?

Hope this helps.

Regards,
David.
