Next to the die there are more variables of which the batch of lead that is used could be a decisive factor.
The way the lead is produced (melting, cooling, stretching, storing, aging) has an effect on the crystalline structure and because of that on the way it responds to the pressing in the die and the rest of the manufacturing process.
It would be very interesting to hear your results!
Thanks for that
I'll update you regarding testing when they arrive...so probably won't be until next week until I get to test them out

I've got a bit of an interesting question for you guys :
I've ordered the following :
Express 4.52 - 42020014 (1)
Express 4.51 - 42020014 (0)
So they are both exactly the same die, just they seemed to have decided that the first batch is a 4.51, but the second batch is a 4.52...?
I'm guessing they thinking the die's may have worn slightly from the first batch, hence the bigger head size for the second batch....but surely if they wore that much they wouldn't be able to do many more further batches?
