Any chance you would expand on your technique to achieve your soft-nose/hard-shank bullets?
You have mentioned these repeatedly and my interest is piqued.
The method takes a little time and as I tried the two pot method unsecessfully find it more accurate as well.
First I cast up a batch of bullets in 50/50 ww/Pb and cut a measured amount from the nose to give me a 65gn portion to put asside for later.I have a hardwood block with an apropriatly sized hole and place the bullet in and mark with a scribe so I can make the cut with a small set of bolt cutters.
The balance of the 50/50 bullets are for general plinking.
Then the lino pot is taken to tempreture and the mould heated again. A soaking wet towel is placed on a chair or other surface behind you so there is seperation between the wet and the pot. Having to turn arround keeps the seperation safety margin.
A nose is put into the mould using a fine set of needdle nose pliers to keep the finger from the heat.
The mould is placed in the pot for a count of 15. I played with different times and found this was enough time to bring the nose in them mould to just short of melt temp.
Fill the mould with lino and let the sprue start to set and return the mould to the pot for 25-30 sec or just until you see the sprue starts to silver off prior to melt temp. It will be liquid enough to allow pulldown of the sprue as it resets.
At this stage turn arround and cool the mould on the wet towel untill the sprue re-sets. This takes about another 25-30 secs.
This is what the two components look like seperated and together. They become a one piece unit in the melt and retain thier integrity through the 2400fps I send them into meat.
These were earlier ones that I cut with a fine hacksaw but find the small bolt cutters give a better cut and easier fit back into the mould.
Recover bullet with expansion from .275 on the nose to .577 with 100% weight retention.
Performance on animals has been spectacular to say the least, with these four falling to them from 143yds out to 185 for the last one.

The best thing is that a straight lino bullet shoots to the same poi for practice etc. I run these over 39gn H4350 for 2415fps from my 7x57. Works for me.
