It was a group purchase of moulds. Nearly a hundred casters signed up and paid in advance. It's up to the individual caster what he will size to. I'll likely try a batch at .311 and another at .309.
These are only single cavity moulds, and while you could likely talk someone, maybe even me, out of a sample batch, you would not be likely to find a continuing supply. Once these moulds are gone, they're gone unless you can find 25 people to go in on another order from Lee.
If you are interested, best check with Aladin to see if he has any unpaid for. Failing that, all you can do is to post on the various cast bullet boards that you want to buy one. Some folks ordered more than one and some folks will find that this bullet does not work for them.
It's going to be several weeks, maybe a month, before anyone has one. The factory is still putting finishing touches on and then they have to get to Aladin to be checked and sent out.
