I've found someone who will make up some flat nosed copper solids for me special order, but the minimul order is for 300 bullets, at 1.7euros each. If anyone is interested, I would be glad to find someone to split the cost with, it doesn't have to be a 50/50 split, even if someone wants 100 I'll send them I just don't want to fork out that much money for these bullets in one go.
Here is a link to Luzt Mollers' website, some of you may have heard about him:

The bullet I am talking about is near the bottom of this page, under "Waterbuffalo in Australia" I'm also going to ask and see if it's possible to makes them 320grains instead of 300.

I'm genuinely not planning on making any money off this and if anyone will take part of the order I'll pay the shipping, but only ordinary mail.

Please let me know.

Those are priced like Belt Mountain's Punch bullets -- an expense I wouldn't spare on the hunt of a lifetime. I have heard good things about Lutz's products.
