Since you specifically wanted a hollow point version,I'm assuming you're focusing on expansion.Getting this without leading is acheivable but may prove to be problematic.With attention paid to bore dimension,bullet alloy,pressure,velocity and so forth,one can get expansion with cast bullets but you may find that you'll have to do some horsing around with variables before finding the balance.
As a very general rule,when one pushes the velocity enough to get reliable expansion and the alloy is soft enough to go along with this,leading is the norm.
Personally (and you may not want to do this),I use jacketed bullets when expansion is what I'm after.
I've used the Lyman 429421 for many years and have only used the solid version.In reference to weight,they've dropped from the mould weighing anywhere from 238 grains to 254 grains,depending on the alloy.
