Thanks for the link Norby. It's got a little over a day left. Not sure whether or not to bid... it's definitely a TC maxiball pictured, but 400 grains. I would surely think it would still shoot well from my rifle, but who knows? May just have to go for it, can't find hide nor hair of a mould for the 430 grainers.

Saw that Saeco also has a .54 maxi mould, but they list theirs at 480 grains.
