I must not be looking in the right places as it seems all of the barrels I've seen cost over $200 and often need more work.

I only have 2 molds as of yet, though I intend on buying a 4 cavity custom mold with 2 different conical designs from Accurate for my ROA.

I asked him to make a FN conical with an OAL as that of a .457" RB so as it wouldn't take up any powder capacity. It came out at 180 grns (if cast in WW) and .460" long. I may adjust the dimensions a little.

The other will be a 250 grn FN.

He also, after seeing that initial conical result in a 180 grn projectile, had him redesign it as a 160 grn, which I was initially thinking.

And then I'll likely get a 320 grn .50 cal REAL mold as my rifle seems to enjoy spitting them down range!
