I am trying to find a source of a good cast bullet for my 8mm Mauser. Lyman used to make a 323471 of 220gn that was the same basic shape as the jacketed military one.

These days Lyman only list a 165gn bullet and Saeco/Redding a 190gn. Anyone know of another maker of 220gn molds?

Try Mountain Molds. He makes custom molds at stock prices. You can get exactly what you want with the online design page. I don't have any (yet) but have heard very good things about them on the Cast Boolits forums.

I don't know how their current quality is running, but I have a 240gr. roundnose 8MM mould from NEI that works wonderfully. It casts out at .327", big enough for all the throats I have tried it in so far. Since you're in Australia you might try the Ammo Dump, CBE moulds as well. Save some shipping if they have what you want.
