RE: A question about casting of my own???
Pure lead for the REALs for the reasons stated.
I find the REALs from my moulds have an increase of about .005 in each "driving band" from the base to the nose. On the 250 grain there's 3 bands and on the 325 grain 4 bands. I would say the 325 would be very hard to start if it were hard lead.
